Can you name even one reason? Besides the fact that the L size is too large for the template, and no one has created adequate content for the M size.
And the main reason is the abundance of critical bugs.
It is the presence of several starting castles that makes it possible to get interesting gameplay in the conditions of early contact. In fact, this is the main feature of this family of templates, and not a problem.
And don't take everything personally.
