If i could choose anything it would be:
1. In-game moderators, so that you can moderate trades, squelch retards so that nobody can hear them, etc..
2. Make anni's and gheeds tradeable (as in the trade screen) so that people dont get ripped off as much.
3. Add some new runewords, so that all characters in PvP have no item advantages. Ex: Bowazon with +3GM faith, archon of the whale with full 40/15, helm of the whale with full 40/15 and high damage psn sc's.
