Making the game harder, is making the players better.
Wide pockets will allow you to "cheat" the pockets on purpose but also allow you to "miss" and still make the ball.
The tight pockets reveal the flaws in the players aim and stroke and requires him to be better.
Taking the ability to cheat the pocket or at least reducing it, is not hurting the game, it's elevating it.
The game has changes many times from the days it was invented. Either you move forward or get stuck in the past.
And yes, player are more cautious and play more defense but the level of defense play has gone up as well as just hiding is not enough with the modern jump cue and how well today's players jump.
Overall, the average pro player today would have beaten the average pool player of 30 years ago easily (no need to try and find the exception, we all know they're out there)
Something to consider, most players that have an issue with the tables are amateurs that these conditions do not apply to them that usually shoot on 5 inch bar boxes (toy tables) and old farts that blame the table for their inability to hit the target...
Pros don't complain about it. They understand that the conditions are even for all and if you want to win, you just have to be better!
