This whole topic is dumb because we are choosing a nominee based on pve and pvp.
From a pvp perspective rage is the highest dmg spec and the ones that need buff/improvements is anni and carnage. Yes i know for some games types like huttball its better to go carnage over rage for all the roots.
But from a pve standpoint Anni is without a doubt the best for sustained dmg while carnage you would use for certain fights where you value burst instead, i dont believe many people use rage for pve.
So for the maurader/sentinel the nominee would have to go to someone who not only knows all 3 specs but also uses them at the highest lvl possible endgame pve/ranked.
Which is why my vote would go to elyvnfrenzy, IGN steadfast(imp)/jawasrevenge(rep). Hes a member of suckafish which is one of the best PVE guilds out there they always compete in all progressions and for world/U.S. first. I dont know if many people know but he used to run with Hey im MVP (one of the best PVP guilds) i think pre 1.7. So you know hes a good candidate both PVE and PVP and very knowledgeable in all 3 specs.
