I've been seeing a lot of no-squadron builds, but even more common are Rebel builds with Shaara and Tycho, sometimes with two more A-Wings. It's almost a requirement. The Empire seems to field Cienna and Rudor (?) as a default, although there are certainly larger aceballs that show up.
The severely stereotyped Rebel squadron play and lack of diversity seems awfully stale to me. I don't mind that as a very good build, but it shouldn't be an auto-include.
