Sup guys, it's spincricket (first post).
I usually farm in Ether once a week, but I stay up there all day. I can usually pull 150M or so if there is no raiding.
I have recently been farming at BM, I can make anywhere from 10-15 Million every 10 minutes if no other race is aggressive. BUT....these mobs hit like hell, and have aggro like no other. I have 201 Dodge, which helps me alot, if I don't one shot these puppies though it becomes...sticky... So I would be reluctant to recommend BM without out of this world DEF or dodge (or a party).
Best bet would be Callis in ether, as they don't hit your MAU as hard as ABA, and I feel they drop more loot as well. Just dedicate one day to farming, and avoid confrontations with higher lvl acc or cora, why waste repair money if you cant kill them?
