Yeah, I honestly think Bistan is gonna be the go-to gunner for Dash, with Trick Shot and Perceptive Co-pilot.

Bistan on Dash means focus action, means far less abilty to exploit Dash's mobility as you have to worry about facing and you're using your action to focus instead of roll/rotate

Assuming FFG actually does their job, Dash should NOT be more efficient than a generic in a straight joust (ie, you actually have to use Dash's ability wisely for him to be worth it).

I think Bistan copilot on a generic YT2400 could be a thing, and hope Dash is too expensive for that strat to be viable on him.
