I think a 20% nerf to skill damage is perfectly reasonable. Skills shouldn't hit extremely hard, be aoe, and CC the mobs for 1ap(cough, battering ram).

I just think it's important to remember that melee should be stronger than magic or it becomes pointless. It's already easy enough to just teleport mobs into elemental fields and watch them die, with no risk to your party. If you can't solo as a melee character, what good is it?

I definitely don't want to go back to OS1's status quo where you had to spend a whole round buffing your fighters for them to be able to kick as much ass as your mages. It was almost always a better option to just spam magic combos.
