Cosmodrome actually isn’t too bad. Once you figure out the bosses attack patterns, and the savathun attack patterns it becomes much easier; u can also suppress him out of his super with suppressor nades, warlock transcendence nade, and hunter tether. But yeah boss fight is an insane slog feel like the map needs to be balanced bit more

I've just never liked the Psi-Ops. I can deal with the other Battlegrounds but those always irked the hell out of me for some reason.
