Once our hero's reach level 50, we start to accumulate experience points that we currently can't put to use. Even tho our hero has reached the highest level currently offered in the game, there are still a lot of hero perks that we have no way of obtaining. I was hoping for the next alpha, that we could use these experience points to earn additional perk points...or add more levels to our hero's so it would balance with all the perks available.
