Re: the Tarquitens
Why not Ozzel? Use that Nav token to change speed by 1 AND add 1 yaw with the Nav Team. Seems reasonable to me.
Where will the Nav token come from? Using a Nav command would be better. Tarkin allows you to generate Nav tokens so you can still CF to get 4 reds.
Comms Net Gozantis and first turn token grabbing, mostly. It's that Ozzel allows for speed changing and a click of yaw on the tokens rather than just a click of yaw (or you can spend it straight up to change speed by 2 rather than just 1). That's pretty flexible (and much cheaper than Tarkin) and should free you up to Concentrate Fire most of the time otherwise.
