We all make mistakes. Here's where you can tell us about ours.

Element Control allowed you to choose an element (air, fire, water, earth) and AP the others. UP split the elements into their own control arrays (air control, fire control, water control, earth control). It provided a way to list unique power types for each element without bogging down an Element Control description. You can still AP each control array if you want.
