Yeah, it's been said to the point of being cliche... but more world under glass stuff. Want to see the ball do more unique things. More magic tricks... like the trunk in TOM or mist multiball from BSD.
Would like to see more use of divertors to make shots into other shots. Seems like that was done much more in the past. Think Shadow. Ramps have become sorta formulaic.
Would like to see modes that feel like they're telling a story... rather than just lighting different arrows.
Agree about giving more meaning to multiballs and wizard modes. Make it clear on how I'm supposed to earn these things and make me earn it.
Simpler rules! Lose this mode stacking tournament bullshit. It's tedious and not what pinball is about.
