Keeping support ships alive
Hi again guys & girls.
I am having a problem with my fleets and i wanted to know if its me, or just something i have to deal with.
I am currently in the Yuuzhan Vong crisis in my current game, playing as the Mon Calamari.
I have a current fleet limit of 355, which is letting me use fleets of 3 Bellator-class heavy dreadnoughts and 1 MC55 fleet tender (the MC55 to keep them alive and repaired while away from base.
I have the MC55 set to use the "carrier" combat computer program so that they should "stay at long range and avoid enemy fire"
I have the Bellator's set to use "picket" combat computer program so they should advance into close range and attempt to intercept the enemy"

But what actually happens in every battle is that the ships form a "flying V" formation with the MC55 at the tip of the V and therefore it dies first every time.

Is there any way to stop this? or do i just have to accept it? I have tried using the support ships in separate fleets, but then they do not repair the Bellators.

Any suggestions?
