I would hesitate to use a monk as they dont have effective taunt.(Not having played one above level 12, I wont say they cant taunt, though I think that is the case.) So if your finger wriggler(s) gets aggro, it will be difficult to get the mob off.
As far as paci pulling it is not hard. The pacify line can be cast on a mob out of line of sight, so all you have to do is have your puller target multiple mobs and cast.It is quite effective at least until you start hitting mobs higher than level 55. Keep in mind the enchanter can pacify as well.
I would still give the berzerker a chance, however just to see how it works out. Its not like your broke and with no friends to help you with zerker gear.
