when fighting HW1 strike craft you had to play to your advantages. You flagship guns are really good at taking out fighters (by design), and you want to be as close to your dock as you can.
The advantage the HW1 player has is he can be precise targeting down one squad at a time, where you have only everything to target.
So the micro is important on both sides, you have to be graceful, using speed to your advantage to bring the fight home to you. The further away he is from reinforcements, the harder it will be for HW1 to get and maintain the upper hand.
Another thing to look for is the supply line itself, when you look up you’ll see a line of fighters coming from his production. Slip one squadren behind the main body and you can pick off and cut off that supply line. If you see the swarm turn to that squad, break off an try to make them chase. That will give your home force time to dock and re supply.
Not saying this easy. HW1 is the rush race. For you it is about survival. But if he puts everything he has into his swarm early, he’s probably cutting in other places like research, he’ll eventually lose the upper hand if he tries to sustain vs a good counter swarmer for too long.
