In short, I'll express my opinion. The idea might be great, and playing fun matches is a good thing, but as soon as it comes to tournaments, problems will start. Therefore, I suggest adding a rule to the Heroes of Might and Magic rules: no rebuilding allowed! And only play with rebuilding by mutual agreement. This way, we can avoid tournaments where, for example, a "Cobra" player forces rebuilding, so as not to divide the community. And, logically, even without control, "truppashers" will crush noobs in the early stages of the tournament, and in the later stages, they will only play against their own kind and with rebuilding.
Actually, that's exactly what was expected... It's strange if anyone thought otherwise:) .
