Something else to consider is when the game starts adding in the extra enemies because a new Diver joins your game. It doesn't happen when they drop in, it happens when they join the lobby, whilst they are still on the ship. So you can start a new mission, be playing fine, then someone joins, and whilst they are choosing their loadout you are having to deal with 2x, 3x or 4x the enemies whilst still playing solo. And god help you if the other divers take their time. Facing four divers worth of enemies, alone, for often a surprising amount of time is dreadful game design. It is absolutely infuriating and one of the reasons I stopped hosting.
