In my opinion, 4 teams in such an unusual tournament is a perfectly reasonable number.
As for the tournaments being held for Heroes 3 and Heroes 5, we plan to have 1 match for Heroes 3 within each round. Well, if the majority decides that the tournament will be held according to the 2-1, 3-2, TE (VT) -1, 4-1, 5-2 scheme, then there will be two matches.
I think this is a perfectly solvable issue; the main thing is the desire.
