I still don't see why "give it boost/barrel roll" is everyone's idea of a perfect fix. I personally think that blurs the line a little too much, and not every ship should have one or both of those actions. The hallmark of the X-Wing as I understand it, has been versatility. I've gone on and on in different threads about rogue squadron ideas, about linked laser ideas, etc. What about this:
In the eu we have 2 seat X-wings, missile armed X-wings, stealth X-Wings, recon X-Wings (although that was usually recon Y's), etc...
What about a title similar to the Scyk, but tuned a little better.
"Specialized Role" 0 points: you may equip either a system, crew, or missile upgrade in the torpedo slot.
If you really want to make it about versatility than make it a little more expensive and make it a card which allows to to equip any of this during setup. It would introduce a "sideboard" to your list and you can basically equip anything you like on the torpedo slot up, paid already by that title so your squad points stay fix, allowing you to customize your X-Wing based on your opponent. If you want to be expecially nice you could for example build it in this way:
Title "Specialized Configuration" 3 Squad Points: You may use this card as any legal crew, missile, system or torpedo upgrade card with a price up to 5 points. Choose which which card this cards represents when deploying this ship and inform your opponent about your decision.
Not sure if the X-Wing is 2 points overcost, maybe the title should be cheaper or more expensive or allow only for 4 points of torpedos, maybe even combining upgrades up to 5 points would be fine (proton rockets + fcs, intelligence agent + proton torpedos), etc
I am sure you get the idea, and I am sure you see that something like this would be cool, but as well a nightmare to balance, because it opens up the x-wing to a lot of options, so I guess having it for free and giving less points to spend would be a lot easier to balance.
