High emblemed or heroes with level 30 troops could be really annoying, so my idea is to strip them in a new tournament mode back to the roots and make a tournament rule where emblems and troops are not considered.
So you can select every heroe from your roster but on the battlefield the emblems and troops are stripped. Just the pure hero.
I think this could be fun and is a possibility for everyone to have the same chances.
Let me know what you are thinking about it.
