I just got a fourth a-wing before wave 4 was announced, but now I'm wondering about the future for a-wings... It seems the z95 fulfills the same role, but cheaper. Even if it's less maneuverable, it's arguably weakening the case for taking a-wings.
Among Rebels, the a-wing was one of the few ships that could carry missiles, so I always thought the a-wing could be buffed with new and interesting missiles -- but now those upgrades will apply equally well to the z95. I guess we'll have to see just how bad the z95 dial is.
Any other thoughts about the role of the a-wing after wave 4?
