I have phantom maxed similar to Ghost. I have tried capital ship upgrades admiral ackbar tier v over 200 times. no luck. I tried all the methods listed here. The closest I have reached is getting rid of rex, jc and ahsoko but Mace keeps reinforcing and clone sergeant's ships have too much protection to overcome at that point. Good point is that at my star ship levels and toons, Tarkin and Mace events were easy to overcome. Akcbar is seriously screwed or something.
