A new Warlock class item
Better customisation for characters
Beta progress to go to full game
was torn on proximity chat, but went with character customization because I didn't hear a single voice all beta & I'm used to it now... wonder what it would have been like. but yeah, there's almost no real uniqueness (yet, anyway). the only way I could tell people apart in combat was their names.
I would personally go for proximity chat, it's a feature that I was gutted to not see in the Beta.
I have seen a couple games like this on my 360 and it had proximity chat on it and I loved it! You could be in dungeons and it would be slightly muffled if the other player was around a corner or in a room beside you! It was awesome!!!
