17 second spawns and spawning super far away from the boat leads to Thorne winning 90%+ of the time.

The only way defense can win is if they hold out on preventing Thorne from being freed. Once he is freed, defense just doesn't spawn often or close enough to have any chance of stopping him.

Reduce spawn times for defense to 5 seconds or have them start spawning on the dock as Thorne gets closer.
