There are a number of ships that have been seen in the Clone Wars or in Rebels that have made it to X-Wing, but there are a few more I would still love to see.
This one could use the idea that no one seems to be bringing up "Bording Parties". A one use upgrade card that could be used on large ships after the touch causing a roll off each round until there is a victor for control of a ship. This would be an interesting counter to a Palp shuttle... or just be a dead boarding party.
Auzituck Anti-Slaver Gunship/AKA the Wookie gunship
This one was in both Clone Wars and Rebels.
last but not least the Phantom II
This one could come with a title card to dock it with the Ghost.
Did I miss any?
For the most part FF seems to source the movies first, then go to the toons, but with all this new stuff it seems like they'll never run out of ships to put out.
Let us know if FF hasn't gotten to your favourite ship yet.
