Board Game Arena

All players know: duel is quitely differ from 3-5 players formats.
And I think it is not fair to play this format as the main.
Most of Arena games are more exciting with 3-4 players. And it is harder to get first place in such kind of games, so more respectfully.

What a .. did you change in dice rolling? Every time ANYone player has 7+ resources-7 in game. And 7 plays more often that usually. Maybe you will let them roll RANDOMLY?
