That's exactly what the PvP community have been asking. Why does someone who does a lot of PvE get to have the best gear in PvP also?
I can understand PvP players being upset. I don't PvP, think I have have 3 player vs player kills and all of those were idiots trying to grief me. People like that gear matters because that is the only thing they have going for them, because it certainly isn't skill or a PvE infiltration shadow or a PvE sawbones would not just destroy them and their pvp gear.
