The LE and pro have identical game play. So likely the pro was just not set up / waxed properly.

Avatar is a great game. One of my 10 favorite in my collection. I haven't idea why it gets so dissed. It's really undeserved.

I recently removed the one way gate to the left of the pop bumpers and like the result. Right orbit shots flow now rather than hit the pops. The skill hit requires some actual skill. Ball is still in the pops plenty. I recommend the change.

I actually recommend removing the navi ball. It ruins the game. Once you experience the 2x stacked multiball scoring, you noonget are satisfied by hitting mb on a standard ball. It also ruins two player games. I think the games better without the navi ball.
