I've never said that any class is better than other or something like that, i just recalled some fights xD And about CCs, i agree that are way better, but not now on warmane, probably after they fix that Aura stacking bug it'll be the best option again, so i'm pretty excited about that.
And i repeat, i think CC is better than DPS, and as you said, specially in arenas, i haven't played too much arenas on warmane yet, so everything i said is based on my experience through BGs and some Duels. But yes, CC on arenas was the king, at least during my period on MoP Official.
