Quick Leveling and Long Life after Upgrade

Ask any MMORPG expert what the main weakness is of his or her favorite game type and the answer you get often equates to: anticipation of happiness is almost always better than the happiness itself. In other words, the hardest period is when you reach the highest level and you have basically nothing to aspire to after that.
What can you do when your character's leveling reaches the limit? Kill other characters; visit other cool places; go to other dungeons; slay dragons; win cool stuff which you eventually need in order to visit cool places, go to dungeons, etc.. In other words, it is a vicious circle, and game developers don't provide a way out and you cannot break it even when you become skilled beyond your wildest dreams. Sounds familiar?
W.E.L.L. Online is built on an entirely different principle. Unlike the usual MMORPG's where most of the time is spent on leveling your character, in our case it happens VERY VERY QUICKLY. But after that a whole endless range of possibilities open up to you.
