That's not even the problem in the whole story. Except for being a retard and merging some DR categories that simply shouldn't be merged ( rofl, horrors sharing DR with sheeps f.ex., goodbye to making a swap on a target that was previously sheeped as a Warlock/SP ), Holinka stated that they want 2s/3s to last 5-10 mins.
Any arena that lasts longer than 4-5 mins becomes a snore. The original appeal of arena was those quick and fast games where one or two mistakes meant a loss, and I for sure don't like headbanging against a wall for 10 mins until stars align and enemy team makes tons of mistakes but simply doesn't die because without Dampening, nothing can be killed. ( bolded part is the reason why 90% of time when I ran 3s in TBC, it was triple DPS to counter all those retards running hunter/2 heals or warlock/2 heals who simply spam mana drain mechanics and wait for 10-20 mins for a single win - I don't fucking understand people who play comps that take shitton of time to win )
I honestly believe I ( or anyone else who's a decent player and not biased ) would design PvP ten times better than any employee they bring on board on their dev team. I'd first restore uniqueness to all healer specs, and find a niche for Monk healers other than "Hey I have this ability on 10 sec cd that makes me not swappable to" and a really clunky healing spell, then I'd try to get DPS specs as possibly balanced as I could, I'd make sure that every class has a synergy with at least one or two other specs in the game, and even go as far as make public polls and actually discuss with decent PvP community, as well as baddies on WoW forums. Tank specs would automatically be banned from arena, I simply wouldn't allow people to queue into arena with a tank spec enabled, which would enable the pve dev team to do whatever the fuck they want with them in PvE.
I think this game would be ten times more fun if we had a player developing for players, not a paid "dev" with zero high rated experience doing what he thinks is best ( which obviously fucking isn't ).
