What are your plans in 5.4? When a new pvp set is available, the item level cap will be increased to roughly 510 in arena and bgs. Meaning, players who PvE will start the season with an advantage over those who PvP. Their gear will already be at 510 across the board, if not higher depending on the actual cap amount. You can't keep the cap at 496 because then what's the point of getting new gear? You can't keep it 496 until 10 weeks into the season when a pvper finally has all the gear. So what's your plan??
PvE gear still can be better where a PvP set bonus is subpar. For instance I have recently been gearing my boomkin. By grabbing shoulders and legs I gain more crit which is not available on the pvp equivalent gear. My four set bonus is not that spectacular for RBGs and the +10% crit to starsurge is huge!
I don't know if it is a bug but the trinkets still have no resilience on them, so besides the trinket to break out of CC, the other trinket is now better to use a PvE one with your pure stat of intellect, agility or strength. This is a huge concern. The pvp power nerf is necessary but not it's more efficient to use a PvE trinket again :(
Also pvp power gems have become a bit useless. Resilience is still arguable about bein useful, for let's say a healer. But the pvp power seems to be subpar to stacking crit mastery or haste. I would appreciate this being addresses somehow. I believe it to be a huge punch in the face to say that PvE players shouldn't feel they need to regem PvP power and resilience everytime they step in arena. I mean, if a pvp player goes into PvE they need to get completely new hear because we are so behind on item level. I think it's fair to say a PvE player should have to actually USE pvp gear to be competitive. They can just start with their PvE gear....
Overall I am pleased with the pvp power change and allowing everyone to have the same base resilience. I'm more or less disappointed with the seemingly unplanned future.
