This should equal out the advantage that the catass crowd had that got their pvp gear before the comms nerf. (remember kids, exploit early and as much as you can)
But I guess this is why there is all this QQ.. Many pvp'ers don't want a lvl field, they want loads of undergeared players to roflstomp and wave peens at.
..Or we could just remove the expertise from pvp gear and perhaps move it to raid gear instead where it only has effect inside raids(no other stat increases on raid gear). Then everyone would be at the same powerbase but with different looks.
But I have little faith in human nature..
