The comp has maybe a 30% chance of getting an uncounterable ship type at the wave sizes they send first wave. Like 900 triangle ships first wave around 5 minutes, plus bonus ship types. We try and stack at least 7-10 shields on the targeted CCs but if they have bombers or something which ignores shields there is very little chance of survival. This is at 7 difficulty.
Wait, wait, wait. What the heck are you doing that you're getting an uncounterable wave five minutes into the game on difficulty
seven? I routinely play with 4-6 people, and while we may lose the vast majority of the time on 7/7, it's been a long time since it's been quite that early. It never, ever sends the waves anywhere near that soon for us (more like 15 minutes, not five), for one thing, and like, it
tells you where they're going. You yoink half the warp gates ahead of time to direct the waves to a couple defensible points, split up your fleets between the systems that are getting attacked, throw down some turrets and stuff to help each other out, and nothing's really a threat until a while later. Bombers shouldn't really be that much of a problem even with just some tractors to slow them down and half a dozen people crapping out fighters in their general direction.
