1.) Fixed realm rates for all.
1.a.) Lower the rates (appeases low rate seeking players, but considerably displeases high rate seeking ones)
1.b.) Leave high rates (appeases high rate seeking players, but displeases low rate seeking ones)
2.) Allow players to customize their personal Exp./Rep./Prof. rate (appeases both high and +/- low rate seeking players)
3.) Have differential/variable rates for realms of a given expansion (i.e., like it was before the molt-down)
