If levitation is in the game id like to see it act more as a quick effect that throws you up in the air a certain height quickly then makes you decend slightly slower than a normal fall. A master of whatever school its under should have at most 5-10 seconds. This should prevent and hopefully make impossible the juvenille dragon ball z and matrix style combat you so crave.
I don't see how exciting aerial combat is juvenile...
and your version of levitation is just jump and slowfall...
The AI is still called Radiant AI and Radiant Story is something else entirely.
oh, my bad i guess i misunderstood. :-p
