BAsically anything a RDM has. I have been trying to play CC on RDM as it's my only comfortable job, and IT SUCKS!! The short cast spells take so long in such a quick environment, I can barely cast, and to get into range to even start to, I get jumped, and either focused down so fast or silenced it doesnt matter. I find myself focusing on the melee skills to get ANY damage done and that isnt something a caster should have to do. The healing aspect of RDM is so useless that it may as well not even be there, and the only useful skill they had got nerfed to be ineffective at all.
