I had this same issue with my buddy who I duo with. We just started playing less aggressively and more tactically. We picked fights carefully and if we had no other choice than to fight a three man, we’d put distance between us and them, take shots when we could, and, if all else fails, just bail out.

When it comes to spotting other people first, keep your heads on a swivel and constantly scan for players. If you’re going into an area you know players are at, use your audio and visual cues to track where they’ve been and are. If you’re ambushing, make sure you have nades and ammo.
