So with the Firespray refit allowing a scum ship this could be a tactic many people see. Using two Y-Wings and a Firespray in a deadly tandem combo against imperial swarms. Example: The Y-wings use ion cannon turrets to render two TIEs virtually imoble. While the next turn the fires pray already positioned near the crippled ties upon revealing his dial places a seismic charge at his last location flying away leaving the helpless in the coming blast. This exact same maneuver can be performed but having the fires pray first place a proximity mine then having the Y-wings force the TIE into it.
So there is my idea sorry if it doesn't exactly work out or if it's been said I just thought I'd give two cents on the subject.
