I'm curious as to what the consensus is on what's the most infuriating/frustrating map to play on. Personally for me a lot of the custom maps are meh.
In terms of vanilla maps i think The Last Stand has the most wipes over it's two chapters For custom maps, Haunted forest is pretty hard and I often hear people don't like the final chapter of Diescraper, though personally I don't mind custom maps being a little unbalanced because of the variety they bring - maybe my opinion will change after I've experienced dying on them all a bunch more though
