If I put a Navigator on Imperial Boba Fett, what am I allowed to do? If I reveal a left bank 1, Boba would let me change it to a right bank 1 and Navigator would let me change it to either a left bank 2 or 3. But am I allowed to combine these and for instance change my left bank 1 to a right bank 3?

Yep! It's mentioned in the FAQ, but basically if you select a bank maneuver you can rotate your dial to any other bank maneuver. Pretty fun in casual play, a bit too expensive and situational for competitive play.

Ok sweet. That's how I played it before. I am thinking about taking the Fett-igator and 3 academies for this Empire Strikes Back themed tournament in a couple weeks. Only ships from that movie, or bounty hunters featured (with a couple more rules) for an 80 point list. I don't think I'll see many Imp Fetts with Vader being the other Imperial ace choice. Definitely wouldn't use the Fett-igator in competitive play though.

The issue with Fettigator is the lack of offensive support.

If you don't mind PS10, Predator offsets that.
