UD are not the best Rogues. The only thing UD gain over any other rogue is the will of the forsaken, most UD's since they have this ability do not use a pvp trinket (im sure theres a few smart ones, but the majority of UDs i talk to do not use it) so all UDs have is an extra trinket slot. BEs really arent all that bad and they make for an interesting chain type stun/spell lock on casters with their silence. Orcs receive an enormous AP boost when they use blood fury (with the loss of 50% healing, but used correctly this should not matter) and have a 15% innate stun resist, very useful vs many classes. Trolls, i just do not like, they look goofy, but im told that berserk is ok :) im really not the one to ask about trolls :).
