YES, I LOVE THIS
NO, I DON'T LIKE THIS
I think what he's asking is to pay gold to drop leagues instead of wasting troops to lose trophies.
For example, if you're in Crystal III and you want to drop to Silver I, pay X amount of gold to do so and not waste the time.
This won't work under SC's trophy dynamic. When you win a raid, the trophies you gain are subtracted from your victim's total, and when you lose, the reverse occurs. If you could pay to drop trophies, who would get the ones you're losing?
