I would tend to agree with you. But if it had more restrictions, like only repairing one point, maybe critical hits that require an action, but when docked they don't require it. Yet on the plus side they might get to keep their defense roll for being under cover.Way too fast. Likely too strong.
One turn in this game is a handful of seconds. No way they can repair a TIE fighter of even one damage that fast.
Hmmm, ok.
Well, don't think of it as repairing... Just the pilot switching to a spare fighter.
As a counter, the rebels have 2x droids who repair shields, a droid who repairs Hull, and a droid who un does ship crits.
If the cruiser carries only 2x spare ties... is that so bad?
I would rather see a "Drop Escort" card. For 12 points you can place a tie fighter next to your base during the planning phase facing any direction. The tie fighter sets a dial and plays just like a normal ship.
More thematic to the Gozanti.
