I'm going to go with Wayne-- I don't think FRC has had one of those in years! (If it hasn't been multipliers, it's been ref judgment calls or seemingly minor rules that have a huge effect.)

As for outside-the-box, I'll go with "house" robots that only get in the way, or that you have to score on. Preferably the latter, as the former has already been done.
