That's probably what Floon means when he says it's not as simple as we think, and that implementing a quick and dirty solution would not result in a feature that made anyone happy; I understand that.
But if Turbine has done a good design and encapsulated the functionality, there's probably a Character object with a operation to called "addExperience". In that case, the change would only be necessary in single place.
