Another example why PvP is what it is; Snipers, you don't see one DSing in WoE, you see them using FA when they do attack, most of them don't even expect to kill. Now a PvM sniper can easily do well in PvP with their high agi/dex build just DSpaming away at people.
Put WoE conditions to PvP and that Sniper is pretty much useless, since his flee is basically worth shit and his DSpam is pretty much tickling all the vit junkies. Then people would have to look at their build and balance things out for PvM and 1vs1 WoE? Don't think so.
