It would be nice to have some realistic pickpocketing (bump and scoot) and non-lethal subduing methods (billy club to the head/tying up) and hopefully a dynamic climbing system! Thieves are part of the "big three" when it comes to RPGs : The Warrior, the Mage, and the Thief. It'd be nice to have some love shoved our way for a change. All the fancy sword tricks mean nothing to a guy who just wants to be a cutpurse.
