idd, the pvp downscaling on heroes doesnt form a good picture, the 2 set bonus from pvp gear coupled with viscous gear itemisation often excel above pve epics let alone their hc blue counterparts.
I know there is a dead stat on pvp gear but for example on my resto druid I have 3 pieces of pvp gear one of which is the wrists for the want of something better and 2 ie shoulders and chest for the 2 part bonus. The main stat above all else by some margin for resto is int, it is so much the more powerful stat that u can afford to loose any secondary stats. The 2 set pve bonus is much much weaker but i still sport it purely for the prime stats on the gear also.
On my hunter agility once again comes out far in excess the most powerful and hard working stat and as the 2 set pvp bonus is agility and the agility on the items is much higher than any hc blues.
I know pvp gear is gunna suffer against like for like pve gear but atm alot of the the pvp gear is better itemised for pve that the pve stuff purely for the much higher base stats. Some classes benefit more for secondry stats like feral dps druids and mastery, but even they can fit in a 2 set and still keep their mastery up by selecting the right pieces...
Yet atm pvp gear pushes down my toons score bellow counterparts in mostly blue gear who not only dont perform to the same lvl, but just cant because the gear is not so good.
