While this feature is very annoying at best without an antagonist, having your progress reset upon host migration when you are almost finished with the objective by the skin of your teeth with an antagonist in the game is infuriating.
A match on BoH with an antagonist. Iune keeps dying for absolutely no reason, Doldren antagonist is so awful that the grunts made more kills than him. We barely downed 2 guardians at the last stage and blew them up. And just as we were about to down the 3rd one.... HOST MIGRATION! 3 lives left before 2nd survival stage, the guardians are back to life, and one player down. WHO DESIGNED THIS?!
