You are going to get shit on 6 ways from sunday on 2 of the NMs
Take a real DD job and get brd to 99, the longer the NMs are alive the better the chance you get quad attacked > qudrastrike or something similar.
Edit: If I was forced to take 3box to farm pops rather than just farm CoP for currency and buy marrows (this is the better option) then SAM SCH/RDM BRD/THF would be best.
