Mix em up use your monk w/ cyclone and crusader with Fist of heaven build not to mention both class has ally buff Mantra and Laws I tried strife 3x demonhunter with 1x monk tempest rush w/ mantra buff works very well

as far as "bang for the buck" not sure what you mean if you mean to make profits, there is no buck to make w/ economy completely dead with everything being bind on account
