Myself I'm gearing with 4 barbs at the moment and I'm going to try and get 3x HotA + Healing Monk for high GRs. The Monk will come a bit later tho, don't think I could manage a uliana monk without going crazy with desyncs.

Also luckily until I get that monk up I have a friend who has been subbing in for my last barb so far this season and he can do the healing monk part.
