It's much less presumtuous than him outright saying it's not a fighting game, and then assuming he just changed his mind. The battle system is also based off a Wii action game. Like nearly verbatum. Adding multiplayer doesn't change its genre.

The Pikachu example doesn't work. Pikachu is only 2x weak to Ground. It would be 1.2x in this case. I said 1.4x for Garchomp because Garchomp is a special case and is 4x weak to ice. But fair enough. Semantics. I'll substitute Pikachu with Garchomp and Garchomp with Weavile.

It's not supposed to be a negligable difference. It just not a game changing difference. In a game with a roster of like 40 characters and the option to switch out to something else that can better handle the match up and other characters who will have the advantage against him, it all balances out. Weavile would have a strong type advantage over Garchomp. He'd have a poor type match up against fighting types Lucario or Machamp though as Weavile has a 4x weakness to fighting, who have a poor match up against Gardevoir being a psychic and fairy type, who has a poor match up against Gengar who is Ghost/Poison, and the list goes on. That's the very definition of balance. Balance doesn't mean everyone is on an even playing field. Balance means that everyone has a check and everyone checks someone else. Types have no effect on that existing. It just changes who checks who.

You can't look at this stuff in a bubble. Garchomp may take 1.4x damage from Weavile's ice moves, but not all of Weavile's moves are ice, and only using ice moves would limit Weavile's combo potential. You know, because Weavile doesn't only have ice moves and only ice moves would be super effective. Weavile is also a fast, but relatively weak character (in Pokken) as opposed to garchomp who is powerful and, you guessed it, still fast with a lot of HP. Garchomp's dragon moves still hit Weavile for very powerful neutral damage Weavile is very fragile, so the resistance to ground type moves aren't going to help it much. Garchomp could have a positive match up to literally every other character in the game but Weavile thanks to that type edge.

This isn't turn based. ALL factors matter in determining a match up, not just types. Garchomp could very well end up having the match up over Weavile because his arcenal is good enough to weather its weaknesses. Saying that it's unfair to have a Pokemon KO'd 5 turns early makes no sense. It's a match up. That's like saying it's not fair that it's not fair that Ganondorf kills Pikachu at low percents in Smash. Of course it is. Sucks for Pika, but that's just part of how the game balances out. Some characters are better against other. If types didn't exist in Pokemon at all, there would still be tierlists. There would still be Uber and there would still be UU. It would just be completely different in who is where. Is it "unfair" that Volcarona get's OHKO'd by rock moves? No, it's just a bad match up, and Volcarona is fast enough and strong enough to take out most Pokemon who would use those moves before they can. THAT is balance.

I never said that assists weren't fair, I'm saying that so are types. It doesn't matter if assists are available to everyone. Types are available to everyone too. You can chose any type on your team, just like you can have any assist Pokemon with any effect. Every Pokemon has a type. I don't get what you're trying to say there.

So types are fair, and types are balanced. That's settled. As for it not being necessary, that's just silly. This is a Pokemon game. Most of these Pokemon would literally not exist if it weren't for the importance of types. Of course it's necessary. It's just not game changing. It's not broken. You're not going to have a match against a type your weak against and then rage quit because you stand no chance.

I don't have to give you a fighting game, because Pokken isn't one, but Darksiders 2 had a 1v1 multiplayer mode that played very similar to Pokken. It had elemental weaknesses and resists. No one complained. You're speaking like you've never even heard of Pokemon types before. Do you even know what they do? Their entire function is to be a balancing tool. The entire reason there's a type chart is for balance. You know what balance is, right? It doesn't mean that everyone can equally take on everyone. It means that everyone has checks that stop them from being the most dominant one and that eventual dominant one isn't so overwhelmingly dominant that it's unfair. That's literally how types function. For types to be unbalanced in Pokken, they'd have to be unbalanced everywhere, including the main games, because their effect is identical. They change the way damage is dealt. It would to it in almost the exact same way to almost the exact same Pokemon. If Pikachu being weak to ground isn't unbalanced in the main games where he'll die in one hit at full health, it won't be unbalanced in Pokken where he'll die only two or three hit's early out of whatever number you make up to represent Garchomp's hits to kill Pika, and he has the tools to block, dodge, counter, and be a better and more technical fighter outside of pure stats.

And switch out to Weavile.

What's the name of the Wii game?

A 2-7 hit difference in a fighting game or a competitive action game is game changing.

No, 'balance' absolutely does not mean every character is checked by another to make a balance. That's the compiled defintion of 'checks and balances' which is a system of counter balances. A system of counter balances are in place only when the characters themselves are not balanced.

Of course saying that a character getting K.O'd 5 turns early makes no sense. I never once said it was turned based. I said 5 hits less, as its a fighting game/competitive action game, and needing to hit less for the same results makes all the difference.

I don't need to guess anything about Garchomp or Weavile, as I have been extesively watching the game. Garchomp has fast and powerful attacks, however, his he doesn't have long combos, which makes pressuring an opponent difficult. Also a lot of his attacks are in fact slow, however he has attacks that come out fast that are meant to close the gap and put immediate pressure, but by no means long term. Weavile, on the other hand, has weaker attacks, but Weavile's attacks come out much faster and string in much bigger combos for pressure, as well as spacing tools, a much better range and speed of distance attacks and several other tools that make it easy to pull up feints and mix ups. What you said, prior heavily implies that it wouldn't be balanced if not for types to set up checks and balances. Its frankly not true.

Its great you brought up Smash, because it only bolsters my point. No, it is not like saying its unfair Ganondorf kills Pikachu at low percents. Ganondorf is a heavy character with low mobility, but is heavy which naturally makes him harder to kill and has extremely powerful attacks at his disposal. Pikachu is a lightweight character and dies earlier than a mid and heavy character, but has moves much more quickly, has better approach options, easier to get many hits, use of a good mide range projectile, and excellent recovery. Ganondorf gives out the exact same damage. He does not give an extra 40% damage to Pikachu. Link/Toon Link do not give Ganondorf extra damage with the Master Sword or any other villan just because its the blade of evil's bane and has an advantage against evil. Mario does not give Bowser extra damage with the Boweser toss throw or Mario Tornado. Greninja does not give Charizard extra damage with his water type attacks. All this in a competitive action game. Every attack gives every player the same amount of damage. Every character has its own advantages an disadvantages. 

Let me be clear about what I meant by fair as I don't think I clarified. Of course its fair to have assists and not types because unlike types, assists aren't tied between specific character vs specific character. Anyone can use it. Then the pie example.

So once again: balance means the character has an strengths and weaknesses in their own fighting style. Checks and balances are a means to substitute bad balancing in individual characters. That's the end of that.

I said fighting games or competitive action game yet it seems you only read fighting game.

Now to be frank, I don't know what you're talking about here. I have never even heard of Darksiders 2 having 1v1 multiplayer until now, which makes a lot of sense because it doesn't seem to have it. I can't find a single thing about it. Even if granted it exist, Darksiders is a hack and slash game, not a competitive action game.

The logic here is strange. You say its merely a catagorization when calling it a competitive action game and say previously there's no reason not to compare to genres. Now here you're saying you won't highlight a fighting game because you say Pokken Tournament isn't one. Subsequently, you compare a competitive action game to a hack and slash game.  If you don't have to give an example of a fighting game because its not in the same genre as Pokken Tournament, why should a hack and slash game, which is also outside the genre, be counted?

Regardless, you can't seem to name a competitive action game that uses factors that give specific characters an advantage over other specific characters. 

Its merely a detriment to competitive, real time games where your direct input vs your opponents bolds the results i.e fighting game and competitive action games. If you're training for a tournament and you main one character, you are instantly going to see people trying to counter pick your lineup based on has an advantage offered exclusively to that character. I can imagine people choosing a character and then rechoosing a character to be an anticharacter of the opponents character because the opponent chose the anti-character in the first place. 

No, Pokken Tournament its not a Pokemon game, its a Pokemon spinoff. Different 'categorization'. I knnow very well what Pokemon types are, and very well why they shouldn't be included (as previously explained). Are you going to say the Mario & Luigi spinoff series should just let you jump on a Koopa, Goomba, etc once before they get defeated or that Luigi's Mansion should be a platformer where he can jump because he can do it in Super Mario Bros.? Should the Pikachu you're maining in Pokken tournament learn new attacks, forget old ones, and evolve into Raichu sporting several different moves too?

No.
