sure, without bigger hotbar there's no way you can fit all the abilities you have at level 27, but still, seeing that you are making some progress is better than being stuck at full exp bar and not leveling up anymore (plus, you can always switch between different sets of abilities). the more new areas we get the more pointless they seem (to some people, at least some just lose interest the moment their characters are maxed out) if you're already on max level. With the new DLC came the disappointment that level cap is still in the game and not even raised a bit.
