It's your game and your tournament/league, though, as a player attending a league you'd have the expectation that the game is going to be functioning 100%. The op should make effort to have the game running as good as possible....and that goes regardless of a league taking place or not. If you have better performing games you'll have better attendance.
That being said every game has it's unique characteristics. If you have to shoot a ball a certain way to make that ramp shot, maybe due to to weak flipper, that's definitely an equalizer for everyone playing the game.
