i kind of like the 3 different xp selections, depending on how high powered of a game your running, we have used different xp tables in our d and d game b4 depending on what the character chooses to do IE, a Litorian from Arcana Evolved in taking racial lvl's is subject to that books xp, so when i was a 6th lvl Litorian(all Racial LVL's) i was accually in the xp chart almost a 7th lvl with XP. keeps the power curve down i think and how a GM wants to run his game
