@The Sceptics,
Currently testing version 5.2 and here are my resluts...
2v2 ~ Frost(Master) Death Knight, Holy(Stun Master) Paladin ~ 2,168 rating
3v3 ~ Unholy(Basic PWNage) Death Knight, Holy(Stun Master) Paladin, Marksmanship(Nucence) Hunter ~ 2,221 rating
5v5 ~ Holy(Stun Master) Paladin, Restoration(Basic) Shaman, Subtlety(Self-Heal) Rogue, Affliction(Basic) Warlock, Shadow(Basic) Priest ~ 2,451 rating
The above, with the exception of 5v5, are full Bot with little to no interfection or manual takover. 5v5 has issues but nothing that the GUI can't leave to manual useage. I tend to go OOM in 5v5 in critical moments, 3v3 is sustainable with manual interjection of WoG and rupts, 2v2 works just fine less I meet a dual caster team. RBG are tonight and I will edit this post to refelect my thoughts on that after a solid nights runs.
P.S. I started using the CC at just under or just above 2K rating for each of the above. As of last night I have gained 100-200 raiting in each bracket. Lastly each memeber above is in full Cata Epics, less the items not availiable in epic form...
