UGLY DUCKLING?
The E-Wing doesn't get a lot of love. There are a few fans out there, myself included, but there is a pretty strong dislike out there for this rebel ship. (No need to rehash that here, by the way)
There have been pages and pages of spirited discussion over the questionable configuration of its laser cannons, but not so much discussion about how it is largely a failed ship.
Only handful of E-Wings saw competitive play this season, to my knowledge all were named pilots probably selected more for their pilot abilities more than any other reason. Corran Horn is doing quite well, in fact.
According to the best mathwing data we have, all E-Wings are over-costed to varying degrees, and the problem is especially bad with the generic pilots, which are estimated to be over-costed by 4 points. No wonder they are absent from competitive tables!
From what I can gather from the articles surrounding the E-Wing's release, it was meant to be an advanced ship, highly maneuverable and packing a variable bag of tricks derived from astromechs and the highly-regarded systems upgrade slot.
The E-Wing has the capacity to be an interesting platform for upgrade combinations, but its main problem- cost, is only exacerbated by additional points spent on upgrades. So we don't see E-Wings in the role they were meant for (we hardly see them at all, actually).
I think they deserve a fix.

Can they make a comeback?
From a homebrew perspective, the easiest way to fix the E-Wing would be a simple points adjustment, bringing the cost of generics down, and lowering the cost of named pilots to a lesser degree. But that sort of direct cost adjustment is not possible outside the realm of a second edition of X-Wing (a dubious proposition; even if it is coming it is probably a long ways off). Also, a direct cost adjustment without incentivizing the use of the upgrade slots moves the E-Wing away from the design space it was intended for- an elite fighter packing a bag of tricks.
Also, any fix will be troublesome to implement, given the power of Corran Horn's ability.
So what fix could realistically applied by FFG?
I'm so glad you asked, Babaganoosh!
The problem of an over-costed ship can be addressed in two basic ways: They can have their cost reduced (i.e. chaardan refit), or their abilities can be modified (i.e. BTL-A4 title).
Any fix also has to come in the form of an upgrade card. E-Wings have access to title, modification, astromech, system, and torpedo cards. And the fix should be as specific as possible to the E-wing (and bonus points if it can favor the generics over the named pilots).
The E-Wing was intended to be an advanced, elite fighter. With that in mind, I've got plenty of hare-brained ideas. Here's a couple of the better ones:
Title: E-Wing series II
Cost: -2
E-Wing only
"An astromech or systems upgrade card must be equipped on this ship."
-This is a mild cost reduction that encourages players to equip astromechs or systems cards, resulting in more appropriately costed E-Wings that have special abilities. It might not do enough to adjust cost though. (Should it be -3? That sounds crazy to me!).
Modification: Engine Retrofit
Cost: 0
E-Wing only
"Replace the evade action in your action bar with the boost action."
-This is a favorable trade of maneuverability for survivability. Focus is also a good defensive option for a 3-agility ship, so the loss of the evade ability is not too bad. On the other hand, picking up boost greatly increases maneuverability, especially in conjunction with advanced sensors. Note that because this is a modification it prevents the use of autothrusters.
What do you think? Can the E-Wing be fixed without compromising its' envisioned role? And can you come up with a better fix than what I've cooked up?
