Just a quick thought experiment on whether using R2F2 to make a Y-wing equal to an X-wing would be worth it. Compared to either the target lock or focus actions it can take, which are of limited uses due to its very low attack and evade, you can use it to match an X-wing in terms of raw stats, especially if you are using horton, which pretty much gives you 3 attack dice. It is a rather pricey setup, but has potential to be that Y-wing setup that everybody dreams of, being a slightly beefier X-wing with ion cannons. Add gaven or dutch as support, and it does seem possible to pull of a Y-wing centered squad.
of course, R2F2 on a X-wing is more efficient, but I believe you now should be able to make the Y-wing into a more fearsome opponent, rather than just any regular damage sponge. Thoughts?
