Quoted from JodyG:
Because many people, myself included, think playfield protectors are stupid. The game doesn't play the same.
I guess what I meant is can they not engineer and create some type of layer that goes over the playfield to prevent dimpling?
Honestly I could give two shits really. My games have dimples on them, nothing crazy, I just don't care. I figure heavy steel ball + bouncing on soft wood and paint = indentations lol
