Yes, you stated it 100% correctly.

The active towerers are "using the system that is currently in place," a system that has been implemented by staff to encourage towering, which it's doing a great job of. I think the rewards are structured pretty well after the GIF change.

Then we have certain crybabies, who aren't capable of "using the system that is currently in place" (because they are bad at towers), who cry about others "using the system that is currently in place."

"Hey, it's unfair that you're 'using the system that is currently in place' when I choose to use the system that is currently in place differently."
It's just another argument where bad players come together and complain because the good players are doing something that they can't do. It happens in every other area of Graal, nothing to see here. Nothing is stopping them from towering to 5000 hours (although I'm sure it'd take them like two years, which is hilarious), just like nothing should stop anyone from towering to 1000 hours.
