I have to say that in miniature games I tend to love aesthetically pleasing lists or lists that fit into the fluff of the setting. That said, I think that X-wing could benefit from Squadron Benefits Cards.
For example, it is very rare to see lists made up entirely of one ship type (other than tie or z swarm) because with so few ships you need to specialize. You don't see 4 A-wings very often for instance.
I think that FFG should encourage some of the fluffy squadrons (as well as using more elite ships with non-character pilots) by giving them benefits if they are the only ships.
I don't know what those benefits might be, but I think that flying 1 Character and 3 non-character A-wings or 1 Char X-wing and 3 non-char xwings would be cool.
Thoughts?
