Do I need Phoenix for ships?

I agree they are a gear sink, but I can still hit top 50 without any of them at g12, I even still have Sabine at g8. I use them both as reinforcements, with Cassian and KRU as my last since I don't have Young Lando or L3 geared too much. Lando Falcon is a good fourth if maxed out since you get all the extra turns. Bistan is better in the initial line up of three than as a reinforcement. I generally call Phantom then Cassian, unless I haven't gotten rid of the first taunt from HT. Usually taunts are gone or will be with the Cassian reinforcement so you can take out Han's Falcon.
