I can't believe people keep saying the Defender is junk. It is something the Imps have lacked, which is an all around ship with durability. Good firepower and agility, coupled with the durability and white K, make it a good jack of all trades. The only bummer is a lack of EPT on the higher generics (something I think was a mistake on the Interceptors to give them) and the skill level should have been greater. In the game fluff for the old Lucas Arts games they were a prototype super fighter to be used by the best of the best, only. For a while, only the first six were built and those were supposed to end up replacing the royal guard interceptors (but then Endor happened....). Why PS1 Defenders exist is a mystery to me. That aside, I think they are a good solid fighter, just not one you can spam. People just have not built good lists with it yet.
The phantom is just fine as a ship, but it did bring the much maligned cloaking from STAW into the game, albeit in somewhat more balanced form. I do think a better mechanic for it would have been to make it 3 attack and plus one on any turn it decloaks, however, which could have been incorporated into the cloaking rules cards.
