Well, I think this manoeuvre is good enough to benefit the pilot, who would otherwise not really get to do stuff in space combat except manoeuvres and escaping, perhaps plot a course... the gunners can always have Precise and/or True Aim
to negate any defensive measures still pointing their way.
Anyway, we obviously disagree on this, I think its better from a gameplay perspective to have it benefit the Pilot and not everyone on the ship, perhaps that is the RAI, perhaps it isn't.
My question then is: if the Pilot succeeds a Gains the advantage check, can the gunners on his ship benefit from that during their turn, the same turn that is (depending on what sort of initiative order you decide to use: per ship or per individual agent in the combat), or must they - like the pilot - wait until the following round to get their shots lined up? If yes: then its no longer very good for starfighters is it?
It's not a maneuver, but an action, hence my opinion that it should be more powerful.
