Not being able to auction them is fine - Gives players more motivation to go out and run the dungeons, which becomes a problem with a lack of involvement in the game when players buy all of their gear off the auction house.
But today in Underground Temple (Expert) I lost a mage shirt to a warrior while I was the only mage in the group because of the roll/loot system thats currently in place.
Perhaps class specific rolls on items that are class specific?
Or being able to trade while in the party?
Need before Greed system?
Loot that doesnt have a class limit until identified by the class who obtains it? (and it identifies to that class).
Loot system is just way to buggy, and really needs to be fixed... Especially with out of guild parties (pick up groups).
Nothing worse than having your end game items be looted to a class that cant use it and you cant trade
