That's all of them as far as I know, combined with the Skill Rune system... this is insane, this game is going to have a ridiculous amount of diversity. I don't mind what they did to the attribute system after hearing all this.
It wont be confusing, maybe it looks slightly confusing now because its all written out in plain word but in-game with the skill trees tab im sure if will be all displayed properly, coherent and whatnot
I don't really mind the name change myself, skill/talent/whatever, I look at it as more of a Blizzard thing than a WoW thing. All the D3 announcements today definitely have sounded good to me so far. The days not over but I'm pretty optimistic now.
