While this isn't quite the original point, I agree with it. If SE had thought about this balance issue, we probably wouldn't be arguing about whether or not the toggle mechanic is clunky or convenient because they would have separated out the spells.

AoE spells should definitely come at a higher MP cost, which would also force us to make careful choices instead of lolspam.
