Something is really, REALLY wrong with those charts. You'd better run them again. Sub is nowhere near that high.
Once again what are you waiting for to buff MM and BM hunter ?3 ^&*!ing phase with 2 garbage spec, and it will be the same on ICC
Sub Rogue, Fury Warrior and Ret Paladin are all beating Survival Hunter? Hunters are in dire need of some buffs, but there has to be a mistake with these numbers.
What's happened that Arcane mages are so high now? They always were but just bored fire mages start respecing for fun?
It's likely a matter of there being very few sub rogue parses, and it just being a small number of extremely skilled/geared rogues playing sub for fun just to see how high their dps can go, and having their friends throw stuff like unholy frenzy and tricks on them. ToGC is very easy content, gotta entertain yourself somehow.
