Better Engine Room
Thrusters have always been a vulnerability, especially for larger ships. You can’t place armor between your hull and your thrusters, for the thrusters need your crews to supply them. While Engine Rooms can supply thrusters, they can only supply adjacent thrusters, meaning themselves must be exposed to enemy fire. I don’t like how everything goes like that.
Engine Rooms power and provide bonus to thrusters within 5 meters, rather than only the adjacent thrusters. You can now place armor between engine rooms and the thrusters, making them less a vulnerability. Also, Engine Room bonus can now additively stack. Two engine rooms affecting a single thruster meaning +100% propulsion.
