Medica II also has a 5y range on Aspected Helios.

Personally I don't agree with the potency of spells being different and that there isn't any good reason for lower potency that you cannot counter with something either the AST or the other two healers have to make them comparable so that the potency really shouldn't be what it is. The main job of a healer is to heal, so the potency shouldn't be any different due to support/utility, which funny enough SCH/WHM have more, and better of, for healing. We just have a lot of use from cards, which doesn't justify it.
