OK, after finally playing The Walking Dead LE at Marvin's last night, I can kind of understand where you are coming from after owning a pro. I have had a pro since release as I was not going to spend the extra for the LE.
I probably played 10 games or so on the LE, the features that are extra just do not seem to add anything to the gameplay at the moment, and very well may make it worse with the damn left ramp. Why the hell they extended the entrance of the ramp past the ramp post is crazy, all it does is create crazy ass air balls and the ramp need to be hit perfect to not get a bounce out or air ball.
The magnets did not work on the LE i played so not sure the difference in the well walker magnet. I am sure its not much.
The drop target and spinner are basically just taking up space.
Cross-bow, blah.. It's just as fun with the flipper and more challenging actually. Corss-bow load and release is slow.
The right ramp fish tank head is cool, but I have laseriffic version so this is not a big attraction.
The only thing I really like is the color changing inserts.
I am sure if I would have started with a Premium/LE I would be happy, but as a pro owner going to a Premium, it's just not that much better and maybe worse in some areas.
