As an Imperial player who loves salad lists, I am looking with a watchful eye on what is to happen to our phantoms. Being super efficient beasts, they are ripe for a nerf. But before they get points'ed out of existence, hear my plea: Let the Empire be the OG house of swarm, but also give it a place for unique frames to shine.
The Empire's greatest strength lies in their ship abilities, behold the efficiencies of the Phantom's Stgyium Particle Array the Defender's Fulle Throttle, and Vader's fearsome ATC. Each of these ship abilities, and their respective pilots' skills can be formed to create a beautiful 4-5 ship list full of both utility and doom.
But, since we see the spamming of these delicate frames, the easiest nerf answer is to cost them so that they cannot be abused.
If we do that, then that also starts pricing them out of being a useful part of mixed lists.
So let's make it easy. Let's make it thematic. Palpatine brings his lessons learned w/ CIS: make Empire ships Limited.
You can only fly two Phantoms. Only one TIE/D, etc. Let the Imperial accountants have a breather (what Imperial Govenor sends 4 highly experimental Phantoms out on patrol?)... That way, you can keep all the base chassis cheaper, as a result, you can have more variety in list building. Empire is fun again. Whee! Do it.
