I’m not sure what happened to the Fewer Hordes mutator, part of me wonders if it was nuked because it was a modifier that made the game easier and yet still rewarded extra EXP, but I think it should be left as is.
It was a great feature to allow teams to try harder difficulties. The first Diff 4 mission I did with my team was a 4 with Fewer Hordes. I think it’s a great way to let people adjust the difficulty in their favour and is another modifier that people would be excited to see on the board.
