I'm really liking the game. There seems to be some difficulty bumps, but then I've just dived into hardcore.
I'm sold on the graphics, the icons are simple and readable.
You lose out on the GUI for character sheets though. I think as a rule of thumb, if changing something on one sheet would change things on another sheet, then those sheets should be view-able together. It's more important to be able to see the individual character stats and spellpower when changing equipment, then being able to change the equipment of all the characters on the same sheet.
