Well the auction house makes getting goodies pretty cool. UO could really use that feature. With that, Luna could burn!!!
An auction house would definitely be cool. I do love the player vendor system in UO but it takes too damn long to find stuff! I think UO could benefit greatly by embracing a type of player vendor catalog system for the entire map (not just Luna); in this way you could still support player vendors but take the hassle of shopping for hours out of the equation. Would definitely add to the quality of Merchant play.
The other thing WoW has over UO is the quest system, I can't believe how extensive it is!
Oh, and the add-ons. Jesus Christ there are a lot of add-ons available for WoW!
There are a lot of things UO has over WoW still, I'll definitely be playing again once my 60-day card runs out in WoW.
