So FF this is what I'd like to see in imperial aces 2:
Tie bomber
Tie advanced
3 new named pilots per ship
Title card for tie advanced giving either an extra upgrade slot ala interceptor or extra pilot skill slot. Let's make Vader the terror on the battlefield he really should be.
New bomb types
Vader always has the problem of being under gunned. So few players take him seriously. I really think Vader on the table needs to be a scary thing. Proton rockets help but he needs a bit more.
