i sell mainly Gems and Epics (lvl 245 bracers are best choice, selling about 2/3 for day). collected as net earnings 250k in about one month.
sometimes do daily with just one grp.
in this way i can play instances, convert emblems->crusader orbs if i want, and buy in ah all mats i need: ores/bars, eternals, etc. fast and easy. if somenthing goes unsold for 2 days in row, i use it
you can do 14/15k for good day or 6/7k for bad day, on my server.
