Disagree, I love pop bumpers and the randomness they add. I wish they were more open in most modern games so they could really push the ball in several different directions. The pops on RZ add immensely to the play and don't just rattle around and then come out a single exit.
Pinball does have skill, but the randomness is what makes it more enjoyable for different skill levels to play against each other. You never know exactly what is going to happen.
