Amazing how many "pro" PvP players know nothing about PvP and just eat what Blizzard serves them.
The most important factor in PvP is having an equal playing field. If people win because of their gear advantage, then for once PvP is not fun but about grinding, and secondly: the 'entrance fee' that has to be 'paid' means less people participate in PvP, and that means less fun overall for everyone. While there has to be some form of entrance fee as of the nature of the game (like leveling to max) it should be as minimal as possible. So there should be some form of easily acquirable gear that everyone can get in less than a day, and from that point on gear should not play any role in PvP at all.
With the reintroduction of critical PvP abilities as a gear reward Blizzard takes a long step backwards. Can you imagine PvPing without CC-breakers? No? Then why would any new pvp player endure that? The essential skills should be available from the first moment you enter PvP without any restrictions.
