The problem is people pick the argument they want to make vs addressing the points made.
It's not 'no dimples vs dimples'. Wood dents.. everyone knows this. Yes, the more dents you have, the less obvious one dent is. So the point of 'all playfields dimple' is true.. but irrelevant to the points raised.
The point of concern is when you see the SEVERITY of these dents and their rate of appearance. When a game 2 weeks old looks like it has more ball play than games 4-5 years old.. that is not the same as things have been.
But no amount of 'leveling out' from more hits will bring height BACK up. So when you have crater impacts (not simple dents).. that spot will be lower.. period. We aren't looking at 20 year old games that have had their PF surface smashed down uniformly to these degrees.
