I have a Thief as a bank alt (it seems appropriate). I have him on enchanting so he can bid on items to disenchant and on inscription simply because it showed up late. I take him out to level up solo from time to time and to train up lock pick. He comes in handy as support. He can also make scrolls, enchant them and send them out for the team or for sale. I also have an enchanter on the main team to DE loot.
