To elaborate, most of the Blue cards in the deck are important situationally anyway. I try to bear Force of Will in mind when making my choices on playing out Blue cards. Holding Brainstorm very conservatively versus decks I know have must-FoW-bombs. Daze and Mental Misstep help hit a bunch of issue cards, but versus NO, SnT, or Jace I tend to let removal or less relevant creatures resolve to have an out.
Post board the deck can adapt easily to support or neglect Force of Will depending on the match up. IE some number of Force can be boarded out against fair/agro decks where Jotun Grunts, SoFaF, Relic and/or Revoker are often helping more. And Meddling Mage comes in over some non-Blue cards (often StP and/or SoBaM) versus decks that one really needs Force of Will buffing my Blue count to 21.
