I elsewhere recommend being able to trade xp in for feats at level 12
I also think this is a pretty good option!
One of my concerns pre-launch was how experience/leveling would be handled, seeing that I was able to consistently reach lvl 5 (max in EA) well before even approaching the Underdark. Now that the game has launched I find myself reaching lvl 12 less than 50% through Act 3 (closer to 25% if you are being thorough). This could easily amount to 10+ hours of the game with no real character advancement and adding 1 or 2 feats in place of additional levels would be cool.
