Does anyone else notice that mutilate/SHD rogues can now destroy certain classes very easily, but have to be quite skilled to kill others? In my levelling blues and Librarian's Paper Cutters I can kill good disc priests in Naxx/PvP gear in about 8 seconds, but taking down a death knight takes at least a minute and I find it hard to kill them at all when they pop CDs and outgear me. It used to be that there was an equal chance vs. every class (except most healers) and skill/gear were the deciding factors.
While it is fun to listen to healers cry and sob about how they don't top the battlegroups anymore, I am also a little disconcerted at certain plate classes' strength.
