I wish they'd get it through their thick skulls that it makes a lot of weapons worthless, especially the Vorpal Sword.
I'd also like to (even though I know I won't) see an update of the classes. Give the thief steal, the Knight cover, etc. I wouldn't mind if they added a couple of new classes to join the fray. Spread out some of the new items from the bonus dungeons to the rest of the world. Basically, redo a bunch of stuff.
