See this is something i would really like ,I craft a lot of furniture for housing and would love to be able to put reagents into a shared bank to trade with my other wizards.
Basically, you have a "shared" gold bank. Since Kings Isle has made most items TRADE, you can put your loot from one character in the shared bank, and take it to the bazaar with another character. :)
Reagent trading might be a nice new feature. I can't wait for the scams ... "Mounts for Diamonds."
