About the fact that the strongest should always win

You are 100% wrong here. You probably have encountered situations where you have no control on high-level maps, while your opponent has 2 air magic books and a spell. You physically cannot gain control. In Warlords, this problem is somewhat solved. You have probably also encountered one-sided maps, which is unpleasant when you hit a dead end, right?)) This problem is well solved in Warlords. The fact that all 4 schools of magic are in demand in Warlords is also bad, right? Now, please answer what your words above in bold red have to do with it?

And if the tournament is called the CIS Championship, then to identify not the best mapmaker, but really the strongest, it is desirable to minimize the amount of such randomness.

And please, let's not talk about morale and experience, as it has been written many times that you can do without them.
