Troll Druids: I think it makes plenty of sense, especially with the Shatterspear stuff that Mikain mentioned (although I'll hate to lose the spot, damn flying mounts!)
Human Hunters: I know a lot of people say they love it, but personally I just don't care.
Gnome Priests: I guess it makes sense, since they've been living in Human/Dwarf society for so long now (probably 10 years or so by Cataclysm?)
Tauren Paladins/Priests: I love that they are making it a form of Sun/Earthmother worship rather than the Light, but it still seems off to me.
Dwarf Mages: They already exist in lore, and we even have one on the server now. Pretty sweet in my opinion.
Night Elf Mages: I can't see Night Elves just accepting Highborne back into their society after 10,000 years of banishment. But that's what CotH lore filtering is for! Still, they could have had Elune-paladins or Shamans instead. Would have made more sense to me.
Orc Mages: Again, they could have added different classes that would make more sense like druids. Honestly, this is the only one I am really against. Still, I have yet to see what explanation Blizzard will come up with, and I would have raged against Tauren Priests/Paladins a lot more if they hadn't already explained that. Give them some time.
Dwarf Shamans: Wildhammers! We've needed this for a long time.
Blood Elf Warriors: Female Blood Elf with Titan's Grip will make me laugh SO hard... As far as RP, I see no problem with it.
Undead Hunters: Same reaction as Human Hunters. Don't care.
Worgen can be anything but Paladins and Shamans/Goblins can be anything but Paladins and Druids: I really think they shouldn't have given the new races as many classes as this. Both of these have more than other races even with their new ones, so really, only about half these classes make sense.
World changes: I am not sure about this. It could provide for some excellent, EXCELLENT RP in the half-destroyed world, especially some events right after the server upgrades to Cataclysm. The main problem I foresee in this is
PHASING. Blizzard has already announced that they're using it even more than they did in WotLK, except this time it will be affecting the entire world. I have a feeling that this will cause a ton of bugs on private servers, and basically make certain areas almost unplayable because of the scenery contradictions. A few questing places in Northrend (Argent Vanguard to Crusaders' Pinnacle mostly) are already completely messed up, and if all of Azeroth becomes like that then I don't know how we're going to play at all. So hopefully there will be some way to fix all that.
From an RP standpoint, I agree that the world changes are awesome. Especially because we're on CotH and we don't have to go by whatever Blizzard says.
