I don't understand this train of thought either. Past 2k almost EVERYONE you vs has pve gear either equal to your own if not better. Using pve items in pvp is not letting gear carry you it is letting gear even the field.
Want some examples? Nearly every dps class uses a DS trinket, a lot of healers benefit from windward heart or the spirit trinket, maw, khaleds, gurth, ratharak, heroic dagger, soul drinkers even, jaws of the earth bow, and kyrill. Then let's add heroic off pieces for certain classes and two set bonuses and we could argue epic gems is pve gear because the material to make them comes from DS only. As for trinkets we have Insignia, soulshifters, vial, bone-link, windward, cunning eye of unmaking, lightening capacitor and i'm sure I could put a handful of more of those.
I think you get the point, FAR too much pve gear on this server to say it carries you no it just evens the field mate sorry. ALL of the top ten teams have pve gear on them. Every. Single. One.
