S elfless E -Wing, X -Wing, Y -Wing, each with Proton Torpedoses. Clickbait-y title, but the squad doesn't seem too bad. Maybe.

• E-Wing of two variants
  • Rogue Squadron Escort (Proton Torpedoes, Selfless, Fire Control System, R3 Astromech) 81
  • Gavin Darklighter (Proton Torpedoes, Selfless) 80
• Garven Dreis (X-Wing) (Proton Torpedoes, Selfless) 59
• Dutch Vander (Y-Wing) (Proton Torpedoes, Selfless, Ion Cannon Turret) 60

All variants are PS 4, with three fully-modded Proton Torpedo shots on the first round of combat. Whoever your opponent tries to focus fire first gets protected somewhat by Selfless on the other two ships. I guess the full mods aren't a settled thing for Dutch's attack, since Garven will need to roll an Eye for that to happen, but it seems pretty likely.

Definitely the Rogue! I'd prefer the action economy to the crits.

Lovin' the whole sharing vibe overall

That seems like a very solid list against other mid-tier jousting lists, but I think you're at a big disadvantage against both swarms and higher PS aces. Swarms will eliminate more of your list than you will of theirs, and nothing except the E-Wing has the manoeuvrability to deal with that. Higher PS aces can simply deny TL acquisition and then close to R1. Defenders like Brath in particular are going to be horrific to try and outplay.

If you can add another X-Wing to your list, They Might Be Giants would be very happy.
