Yes, of course, it's best to ban Diplomacy and play with all heroes except Sir Mullich.
I also have a small suggestion for the tournament format - what if we don't have a tournament, but a championship! That is, everyone will be in one group, and each plays against each other, and the winner and all the remaining places will be determined based on the total number of points!
Зло как и добро имеет своих героев!!!
