For starship combat I would suggest we take a look at the ships and decide if we want to use the Pegasus or Drake beforehand to avoid a long debate during game time. (I assume we get to use the Tier 4 ship for a tier 3-4 scenario, rather than having to round down to the Tier 2 ship for an APL of 3). I prefer the Drake overall and it has a good weapon setup if we are running with 3 gunners, but the Pegasus has better maneuverability and sensors.
I'd nominate Wex as pilot despite my unfortunate history of rolling 1's for piloting checks. He has a decent skill bonus (+9) and I have piloted a couple of space combat encounters before so should be able keep things from bogging down in the helm phase.
I would tentatively suggest the following crew assignments:
Captain: Pregen Envoy(?)
Pilot: Wex
Engineer: Hellin5 or Cassie
Science officer: Technomancer
Gunners: Cairo; Soldier; Operative
