This little and nasty toys are now a recurrent resource during casual play in my local LGS. Ep 4 ships are seen very often in games played between mature players. So you can see quite often one X Wing or Y Wing so equipped, or one ARC 170.
The key to its popularity is that you can shoot them in the Action Segment and then fry the unfortunate target with your turret or main armament. And the Combo "Shoot the m and somebody will give me a TL for my proton" is also popular.
Remove that rock from your LOS. 50% chance of hitting that high AGI target. Then Proton launch unobstructed. Perhaps not the best way to win professional tournaments but quite funny
