Repair Buoy for Carriers

[Titan*]

Carriers should be a support ship so here is the idea;
Repair Buoy only deployed by Carriers and repairs all ships within radius(also enemies). It should have cooldown time (5minute or less) and Active time should be 30 seconds
After 30 seconds it will disappear. It should repair only Fighters and Bombers.
Of course it will repair capital ships too but it will be like %2 or %5 (For Battleships, Sub capitals will get more Hp)

So What you guys think about repair buoy for Carriers?
