Thank for all the answer. So basically, Drg is mixing class then. a melee Dps that reduce dps a little but gain some support and AoE sound about right. (Or could say that he is burst DD, but really not so much useful imo about burst since there aren't so much situation that need it, and most of the time other dps combination can over come that) About whm vs sch debate, I would leave it to healer forum, but I disagree about Sch not stronger in single target heal. As you already stated condition "without Lustrate", Well, Sch is supposed to have Lustrate, it is one of key performance ability.
My static T6-8 keep raining with Monk items. Didn't expect your case that your static always get Drg gear lol, in my case, we only seen 1 gear in 2 months. We already assume that Drg gear has lowest drop rate.
