Anyhow, yeah, this was bound to happen, but it is not a bit more frustrating (in fact, it is way less frustrating, imho) than being CC'd the second I pop aura mastery/wings on my paladin, being CC'd the instant I start to cast penance, etc. It sucks, but uncounterable crap really has no place in the game. Arena, in my opinion, should be a game of moves and counter moves, more chess-like than anything else.
