I would like to see some type of stealth. Say you have a small stealth unit on your ship then the enemy detection range on your ship is reduced by 1 core size. I.E. you have a medium core with a small stealth unit makes you have the same detection range of a small core. Or you have a large core with a medium stealth unit that also makes your detection range, as in the enemy detecting you, the same as a small core.
Once they implement power in the game I believe a lot of this will be balanced. Enjoy the meta while you can.
