Since Integrated Astromech came out, I've been trying to give my x-wings an airing to get a feel for how much IA has improved them, and whether it's enough.
General feeling is that they've undoubtedly improved, but by a small margin, it's not quite enough
Seems to me that the mandatory minimum 1 extra point you need to spend, and the general lack of choice in the 1 point astromech category is just enough to stop them from breaking back into the big time.
So the solution seems pretty simple - provide some more 1 point astros, find a way to reduce the cost of (some) astros, and possibly introduce a 0 point astro or two.
Idea #1 Title Card (Rogue squadron perhaps?) - 0 points
You may reduce the cost of all 1-3 point astromechs by 1 squad point
Idea #2 - Double sided 0 point astro mech card ( perhaps R1A and R1B )
R1A - Once per round when attacking, if you have a focus token, you may change one of your blank results to a focus result
R1B - Once per round when defending, if you have a focus token you may change one of your blank results to a focus result
Idea # 3 - both of the above, but Increase the cost of R1A/B to 1 point
The R1A/B abilities seem pretty stellar - if a little situational - for 0 points
