Bang bang
Your racial setup really screws up your to-hit chances, so you will always be at a disadvantage. The fact that some of your ships didn’t have maxed sensors doesn’t help much either.
When your ships have less chance of hitting than your opponent, the ONLY way to go is: Point blank – Break formation – Nearest first. Looking at the replay, your ships just got stuck in traffic, everybody trying to get at a ship having a little damage. If such was not reachable they just wasted their shot at a random ship at max range. Not easy to win battles with a 1% to hit chance
Don’t think using regular weapons instead of racials would have made any difference. My ships are heavy with Crystalline armor and pretty hard to kill anyway. The way to go against Crystalline is Shield depleters and then the biggest gun available. Those “red globe thingies” (forgot their name) you got should be pretty good if you can get close enough to hit.
