Blizzard sold us on the idea that by making resilience base across the board, and adding PvP power to PvP gear, it would create an environment where PvP gear would be ideal for PvP, BUT you could still participate in PvP wearing your raid gear without feeling like you're getting blown up.
This would work, were they to stick to the model of each season corresponding to each raid tier. But at the moment me sitting in nearly full Grevious gear, I find myself completely outgunned and getting blown up by a PvE geared hunter who has a good 12,000 more Agility than me, and a good 200,000 more HP than me.
I appreciate them making PvE gear nearly useless in Arena due to the item crunch, but why have 522ilvl PvP gear out at the same time as 560+ PvE gear??? Is this to discourage raiders from feeling compelled to farm PvP gear as a starter set? If so, was that REALLY a problem that needed fixing, at the cost of screwing over the entire rest of the game's balance?
