My shard is currently mostly Ghost, Phantom, Biggs. Most like a Vader in the back (perhaps a Consular if they haven't got him), along with a Boba.
Not many seem to have managed the 5* challenges aside from myself and the top end.
Doubt the last two ships released have inspired any variety either. I didn't have long with ships 1.0 before 0.5 dropped so I don't know how things used to be.
