TIE bomber has no pilot?

None of the ships have "pilots", most of them have "Crew Member(s)". ;)

I agree, this is an inconsistency, and a missed opportunity for ways to improve your fleet.

IMO, They should not do crewless ships if they can throw in a pilot toon to work on as well to make sure you can be better than the other players' ships. The droid ships are of course exempt.
