The people that need a casual mode would not play online. These are the people that are just in it for the story and some liesure fun. The bolded is a non-issue. Do people that play CoD or Street Fighter campaigns on easy only play online? No... Of course not. They didn't buy the game for competition and challenge and what they do play has no effect on the people that are there for competition and challenge. When they do go online for shits and giggles, they get wrecked if they're not paired with another casual player. The same would simply be true for a racer and a souls game.

So give the casuals an easy mode, but essentially a limited version of the game? What if two casuals want to play together? What if a casual and his friend, a pro, want to play together? Suddenly they cant.

Part of the fun of souls is the difficulty. Take out the difficulty, you take out the fun.

You're essentially saying that the people that played The Last of Us on Easy played a different game than the people that played only ond Survivor/Grounded. Arguably true. I probably couldn't have fun on easy, but that doesn't mean other's can't. Both sets of TLOU players can get what they want out of the game. If someone has a problem with how the multiplayer works, they simply wouldn't buy it or play offline. I have no problem ignoring TLOU's online and playing offline in Bloodborne. (I win most of the time with DS PvP, I just don't care for it. Also don't like getting help.) 

If they want to play together, they play together. The pro wins either way game.... like I just explained.  This is literally a non-issue.

Fun is subjective. 

King's Field should get a new start as a reboot (like Ratchet & Clank). This would be the best for King's Field!

I feel like asking for a casual mode does truly defeat the purpose of the Souls series. Casual modes are for games that are able to be story driven. If you haven't played a Souls game, you may not get it, but they are far from story driven. You just vaguely understand why you're doing what you're doing half the time, and sometimes progression comes from a path simply being the only one you could find at that point. The Souls games would just get boring if you could plow through everything with minimal skill. A lot of the fun from the Souls games comes from getting better. From gaining more skill as a player. I mean, I suck at the games. They have made me rage so, so hard. Yet I would never play a casual mode because I feel that would undermine the very core of the series. By sheer practice and willpower, I've made excellent progression through both Dark Souls and Dark Souls 2.

If you really are willing to tell me you'd play for the vague lore and otherwise fairly barebones story that you'd probably have to youtube later to get a comprehensive analysis of every little bit of lore in the game, well, let's just say that I hope you never have any direct influence on a Souls game. Ever.

The last of us is incredibly story focused. The only difference between all difficulties (which i've completed) is enemy AI are slightly better at aiming and less scavenging items. At easy mode, you still get the experience naughty dog is selling, a great game with great gameplay and an even greater story.

Bloodborne/Dark souls, while always has a deep story and an even deeper lore, is not the fun of the game. I jumped head first into bloodborne and had no clue what was going on story-wise. But I had a blast learning combos against tough bosses and learning from failure. People enjoy bloodborne for the gameplay, the tough hardcore gameplay where you dont just spam attacks, you learn combo's and enemy patterns in order to better attack.

Now say they add an easy mode. You'll be going from boss to boss having absolutely no trouble at all. What satisfaction will you get out of it? "Oh I just spam attacked and killed 15 bosses and now the game is over"

From Software doesn't want that to be the experience. They want the players t have the best way to play or no way, otherwise it's just another 'mash r1 to kill' game.

To add, you can easily boost your levels to make yourself more powerful in BB. So if a casual wants in but cannot handle it as well as a vet, he will have to boost and level up, or just give up and accept it is not his type of game.

And ofcourse mp is an issue. One casual and one normal mode player teams up, what does the boss do? Just aim for the normal player so the casual can spam him? Or does the boss' AI decrease to casual level so both players can spam him. I struggle on a couple of bosses in chalice dungeon, if some of the random cooperators who helped me made the boss super easy, I would lose that satisfaction of defeating the boss. A casual would be ruining the game for someone who enjoys it for what it is.

Exactly! Some devs care about the player experience, and being able to spam a boss to death defeats the purpose of what makes souls so fun for a seasoned pro. Most people don't even understand the story of bloodborne (me included) without going to a youtuber like Vaati who does it so in depth. 

The lore may be insignificant/confusing/irrelevent to guy A but that doesn't mean it won't be fun to explore for guy B. In my borderlands party, there's one guy that finds the gameplay boring but enjoys the story, another the loves the gameplay and ignores the story, and me who completely ignores the story and finds the gameplay mediocre and just enjoy the side conversations with my two buddies. Just look at forums about DS/BB and you've find several people in enjoying conversations about the lore and world (Conversations about item descriptions, scenery and cutscene significance, etc) rather than discussing combos and attack patterns.

Cutting out the people that want to explore your world and not spend hours "getting good" doesn't make sense because it isn't necessary to keep the game enjoyable for the "hardcore" guys. The presence of a casual mode just means more people get what they way.
