Personally it would make the scount a more essential ship to have in the fleet and keep the balance in the game.
1. Research the ability to detect and destroy mines.
2. Second research on ability to detect and paint a cluster of mines for the fleet to destroy.
Maybe having the starbase emit a jump nullifier and tractor for an area of 270 degrees of the grav well. The area is provided when you make the starbase so you need to pay attention a little. That way a fleet still has the option of jumping out of the system back the way it came but cant go around the station as they will get drawn towards it and its weapon range. Its just a thought but it might solve the problem a little.
Please however argue the point if you dont think it would work.
