Even beyond that,  anyone that can't admit the amount of frustration that can be associated with playing on Hell difficulty in very difficult dungeons and dying simply because the game is too buggy to handle it.  Health pots not working how they should, etc.  (In before, your just not good at the game, etc) Anyone who has played D2 can attest to this being an annoyance. 

I want a total challenge with Diablo 3 (Like D1/D2 could provide on the hardest modes),  But I want the game to be a lot less buggy and more 'complete'.

Who give's a crap?
If your a hardcore Diablo fan, like I am, you will get this game.
Cmon guys, I would want for it to be like Diablo 2 as much as you guys, but they have to move on, this is no expansion, it's a whole new game.. With a new development team.
It doesn't look like WoW, it has some features WoW has, so what? Diablo is an RPG, and will stay like that, WoW is a MMO, and it will stay like that.
Your bashing a game on how it uses fury instead of mana, it's a good move, because casters should have mana, not barbarians.
Skill tree's? Theres skill tree's in Diablo 2, why are you complaining?
And the inventory, I don't see anything wrong with it, like I said, its a whole new game.
The health orbs, I don't really care about it, as long as I gain health some way.
I know I will be getting this game day one, no matter WHAT.
And I know that there is millions of people out there like me, that can't wait to get their hands on this game.

Diablo = Diablo... WoW = WoW.

Stop comparing the two.

You do realize that the Skill trees similar to WoW's talent trees nowadays? Also that the Barbarian mechanic is the exact same as the warrior mechanic in WoW. Also WoW is an RPG, more so than most RPGs out there tbh so comparing these 2 games is quite easy. I'mgetting the game, but my expectations have been heavily reduced than what they used to be. As I said, next thing you know they will add a melee damage calss (to replace assassin/amazon) that will use energy, just liek the rogues in WoW do. No thank you.

And Wow skill tree was heavilly borrowed from D2 so it's just going full circle...( where do you think wow got the idea for 3 skills tree or stuff like whirlwind, corpse explosion and such ?).

All you're saying there is that D3 is taking stuff from D2 through Wow....

Actually initially those weren't skill trees at all, just outright talents. Now they became more like skill tress over the last 2 years. At the same time, D2 didn't have the "you need 5 in tier 1 to get tier 2" which would have just fucked up diablo 2 as well. The things I mentioned were in no form in Diablo 2, and only contributed to a number of problems in WoW.

- No potions (I know mobs will drop health, but there's a world of difference between starting with a potion and hoping for a drop)
