so far i know Adoc, Slaanesh, Bure and Bure's friend and myself.
Remember this game rewards grp play, most quests are very grp friendly and the grp xp loss per kill is very low, moreover do most classes have abilities that helps the grp besides dps (meaning CC, spot heal, protection skills etc.) hence grp = good
