Satisfied. In my view, once the party gets to the BBEG, the BBEG is already dead and just living on borrowed time. If the barbarian charges and gets a lucky crit with power attacking, and the BBEG fails the massive damage save, then he is dead.
If the wizard carefully saved his one disintegrate for the final fight, then he deserves to get to use it.
And fudging initiative? If the fighter took a ton of feats and raised dex to boost her initiative, why would I fudge initiative?
