Diablo 3 - System revisions & Blue post discussion

Frankly, I think, that most of Diablo fans are disappointed of what current team of Diablo 3 is doing, because I get the feeling, that that team, that is working on this sequel doesn't know the hell of what they are doing and don't know why Diablo 2 (incl. Lord of Destruction) was so popular and still is.

Starting off the question about why the hell they changed characters in the game? The barbarian stayed, every other class is gone, why? Was it so hard to remake the classes? There are more classes in Diablo 2, than in Diablo 3, which is pathetic. The more you look into Diablo 3, the more it reminds WoW rather than D2, especially with those comic figure looking player and monster models, not mentioning, that the graphics aren't as gloomy as D2.

I sure hope they won't mess up the world random generation, since that might be the only thing, that will resemble to D2, everything else isn't, but that's my opinion and is based on the information spread across the web and no actual gameplay.
