yeah, but at the same time BBEGs will have plenty of tricks that won't be affected, or at least not as much, by it. They'll have either more attacks per round than you will, spells that don't require attack roles or saves, more HP, and plenty of minions.
Plus, they could simply ignore you. Unless maybe you were a knight and kept challenging him...
