I have an idea, and Spiros T told me to post it here.
What if all the Town Hall 11 and 12's only attacked other Town Hall 11 and 12's no matter what league they are in?
The lower leagues are filled with Town Hall 11 and 12's that Town Hall 10's and below do not stand a chance against.
This could prevent rushed players from jumping to these Town Halls and would give Legends league players more opponents and less wait time.
