Honestly i would use my DK profile, (warmane donor account.) make 10 dks and level each to 70 and get all alchemy up to 425 on all, (i can make profile for you if you wish when i get time.)
and just make gems / sell them, 1 epic is 200
so 10 * 5 = 50 gems, 50 * 200 per = 10k per day * 30 = 300k per month * 12 = 3.6m per month, No ban or anything, (abusing the game as is, not using farm bot and you can config @Droidz relogger to log each other account and toon to make a gem and put into a gbank with only one click. this is your best bet for save gold no ban.
