But can they keep the listing of item to sell attached to the account?
Basically remove the Search Tab from the AH and BOOM it a store system.
People can right click on other players and view their store!
Upgrade required: Be able to list more than 10 items (20-25 plz)
Only players that recently played with you, in your friend list, in chat, that have access to your account in the recently played char can right click on your name and select View Store.
Keep the fee for RMAH and AH system but make it a store system...
Allow people to still sell gold to other players for real money, but by using the store system.
Basically if people want to buy cheap gold, they can do it using a legit system instead of 3rd party website.
The issue of the AH was that finding item and comparing item made it too easy and there was too many item, making lv1-59 to easy to level up with the AH system. When we are at CAP level, there will always be people selling the best item or item to upgrade based on your player.
Ideally, it would be nice to have a public game were more than 8 players can join to chat and trade item and dual, no pvm... I would love it if we could be 20 in a game for pvp/brawling.
Needless to say... don't allow 3rd party website to list items of all stores of all players to re-create a search engine for items. Basically everyone has their circle of friend and they can buy item from their friends.
