I know there are some variant rules on bgg and the sde forum to make arcade mode more difficult/less of a loot fest and faster, but I would still like what works for people and what dont. I was thinking about, in a two player game, starting with only 2 heroes, 2 tiles and only getting loot by killing elites? Or have someone found another simple solution for reducing the game lenght and the overpowered heroes in arcade mode?
Close to the end of the rulebook has some tweaks that you can put into the game. Those work for me usually.
