Let's talk about evolution, here. The game needs to evolve to make it better.
Take basketball, we're not still shooting to peach baskets, are we?
Baseball, football, even soccer have changed.
Just because some guy invented a disc-catching device doesn't mean that the rules or the device cannot change.
Excellent point, but I think that the answer here is changing the targets, not the rules. Allowing DROTs fundamentally changes the way we aim at the target, it would be like saying a soccer ball that hits the top crossbar is good for a goal. I agree that we need to do something about the fact that our targets can "catch" in a way that's not really a made putt, but I think we should address that by changing the standards for targets rather than changing the rules of the game.
