Drawing from a concept explored in the Halo Fleet Battles game, combined with the new stands for flotillas, it occurred to me that you could in theory, with existing components, create a new ship type; Formations.
So a formation would have the flotilla stand(a new stands would be required for some small ships that use a keyway slot) and two different models on it. Like a Nebulon and CR-90 for instance. Or a Gozanti and a Decimator. And then get some specific game effect for having the ships together.
I would love to see that. Opens up a whole world of possibility for designs without really mucking anything up, and using content players would already have or easily get. Would be perfect is they want to do more expansions without models like Corellian Conflict.
