If you want PvP you turn your flag on. Or join your very own server.
I don't see how it makes people who want to PvP unhappy since... THEY CAN FLAG THEMSELVES.
Instead of everybody being flagged, even if full-blood PvE players. How about that part of the MMO-society that is fine being walked over?
Sure, next time I will LFG I will specifically add non-flagged. Since healers aren't hard enough to find already, true?
