If two of those eight fireballs hit from meteor than it was worth the AP.
say that happens 50% of the time.
that STILL makes just casting fireball more efficient.
I will remember your remark on my next playthrough. The last one was a little disappointing easy, because of starting with double meteor shower killed most enemies before the first turn, I guess I have to do this next time with just two fireballs.
If that does not work I gonna spam you with complains about your suggest strategie. ;-)
