The idea that the main hero can only be a hero of the chosen race is difficult to implement:

And regarding Luna, I think the wall's strength effect should be reduced to +40 on Expert Fire.

that's too harsh, I think it's possible to reduce the wall's strengthening by 25-40%.

And is this a discussion of the tournament rules or generally how to change the game?
