Too many stuns, too many interrupts, too many slows. That's the whole experience I got from starting to play PvP with Cataclysm as a Shadow.
Shouldn't it be either CC or massive damage?
I don't know about you but "not being able to do anything" is the exact opposite of everything that's fun for me in games.
Can't really say anything else about it I think.
I'd really like half of the CC in PvP just taken out of the game.
