So, you started with a full AI crew, on a double hades pyra. The AIs shoot the hades consistently, repair them when they get broken, and react to pilot commands. Then a clueless level 1 gunner joins with heatsink, heavy, loch, chemspray and phoenix claw. RIP.
Suggestion: Automatically recommend loadouts to mid-match joiners. Maybe give them all 3 choices set up by the captain.
