that's a nice way of looking at it, steel...
unfortunately most see it as a grinding system, including the wiki itself. they have a detailed description of exactly how to build a tower, for instance, that allows the greatest amount of xp on acrobatics by dropping off a number of ledges, taking the fall damage from each but not dieing, and finally putting fire/lava beside the final landing spot. couple it with a bed at the top of the tower, and congrats you have an acrobatics grinder.
also, the fastest way to grind mining is mining a gold ore, then placing it back down. repeat till max level.
Like I said, its not a bad plugin. I think some of it's uses are interesting, such as bringing axes damage up so that they are also a possible weapon choice, and the different right click attack bonuses they give gives a more options for pvp combat. I just don't like how hard it promotes grinding of things you wouldn't do normally, like the two examples above.
