I level because EVERY level is AO is a reward. Occasionally there is that nano that catches your eye that prompts you to level quickly to attain it, but for the most part you are able to use new gear and or formula just about every instance that you have leveled a few times. This level limit game Funcom is playing will make AO just like all the other exp treadmill games out there right now. Another reason that I level is because there is no reward for staying at the same level. If there were perhaps some sort of activity (besides currently pointless pvp) that would reward staying at the same level then characters wouldn’t be in such a hurry to advance.
