I'd make some kind of thrower for duncraig and fauzt, maybe with snake stance.
For bremmtown axe barb is actually good, especially with aoe from some source (axe or helm), goes through it very quickly.
I may upload video how this clears with endgame gear and ppl can judge if thats fast enough for them.
Generally speaking if I wanetd to really go hard on mfing, I wouldn't play barb.
