Training is not fun.
So don't train. What is the worst that can happen? Duels will actually be risky? You won't win that tournament that was so important to you having fun?
Having others spend huge resources on training is not fun.
I'm not having less fun because my neighbor likes to watch baseball. I don't understand how that could happen to you.
Gameplay-wise, there's no reason to have academies around. People who want to train should pressure their leaders to hold more tournaments.
If you don't like academies in your realm, destroy the academies there. It'll save you maintenance money.
