I think the real issue here, is that nearly everyone knows that the X-Wing still needs something, but we can't agree on exactly what. But maybe the real issue is simply that the game X-Wing has changed so much over the last 8 waves that a ship like the X-Wing which is a pure jouster simply can never be truly viable in this game.
Good point - sadly....
In some ways though, the x-wing isn't all that different to any other ship in the game - plenty of options, but only a couple of genuinely optimal ones when it comes tourney time. Biggs has come in and out of vogue a few times but always seems to find a way to make a comeback - Wes seems to be having a minor renaissance at the moment - maybe that kind of scenario should be good enough.
After all, is that so different for the other ships?
The TIE Advanced has been "fixed" but nonetheless outside of AC Tempests and ATC Vader, what other builds do you see?
How often do you see a named A-Wing pilot that isn't Jake - or Brobots that aren't B and C?
Name any ship type and there will always be pilots that are overlooked and pilots that have some utility.
But anyway - moving back to the topic - perhaps another approach to capitalise on the IA "fix" would be to produce a range of unique astromechs that are specifically tailored to each of the unique pilot's abilities - cost them according to how good that particular ability is - but offer a discount if it's equipped on a specific named pilot
A 3-4 point turtle-bot that's 1 point on Biggs (when you perform a focus action assign an evade token to your ship) - a similarly priced Recon-spec-bot for Garven -4 point Uber-arc-dodging bot that's only a point on Wedge ....... or something like that.
