Chaos Wastes are almost impossible to finish because of broken connections, getting host migrations, or random black screens that instantly kick me back to main menu.
Just had a game where we got host migrated 4 times in a row! 70,90,270 ping. Who does the game decide to be host? The guy with high ping! So now we have 300~ ping each, all so the one player could be host. Naturally the game kept cycling hosts and we would die and the game ended in failure.
