well, back in my gold selling times i was using 4 (1 AH, 2 farmers, 1 proffesions) but now im stick only to main and a farmer as i only need g's for mounts.
37 I think. 25 of them are from that 2? battechest deal, just to test the limit of my comp and if they make the money back in the free month.
For testing purposes I need an assortment of characters or different levels and classes. I usually have something on the go all the time just to fill a level gap. Currently I have 4 accounts dedicated to farming. I have recently purchased 2 more for that purpose. Not for selling gold but for getting the accounts banned. I'm trying to see what it will take to get an account banned with Farmer Joe. So far both have been running for in excess of 18 hours.
