So far from what I've found is I use my PVE that was once good but now noob (63's). I make sure none of my gear has expertise in it and I get 1900 expertise. I wear my mixed EWH/WH set I get 1400 expertise, lower dmg/healing and HP, then get beat down twice as fast as I use too ( because nobody guards the healers in pvp) With the PVE get much better results. Expertise gear will make a difference at 55 but I think until then its a handicap. Naked is better than war hero gear for sure, but pve gear destroys EWH for the current bolstering system.
