Quoted from Who-Dey:
Possibly true but I can tell you from experience that my TWD and GOT both looked really bad and they look 100% better now after 1600-1700 plays on them. Not sure if they were that bad or not but they had some massive crater like dimples in them. I do believe the camera makes it look a little worse because he is zoomed in big time when he took that picture.
I've had a couple of TWD and all get some dimpling in area by the upper magnet and in the center of the playfield. Those were all just minor clear/wood depressions from air ball hits that definitely do get better over time and slowly go away. This SW is pretty much a brand new game with craters instead of dimples. It might get better over time but that crap is not going away. A few BM66 has similar issues. It almost looks like the cc is not properly cured more then the wood is soft. If you look you can see large ones were the cc had been shifted buy the ball strike. Definitely not normal or OK in my opinion. Likely just a bad playfield for whatever reason.
