When I play Aeon, auroras are awesome in the early t1 phase because of their range. But a commander with the gun upgrade can outrange auroras AND destroy that in one hit. Combine that with some light artillery to remove point defense and overcharge to smash early T2 PD and vet up, and I really don't see much Aeon can do. Even mass swarms of Auroras just get grinded to dust, and at this rank most players I face will just micro around fervor's low AoE.
I've tried going for gun commander of my own but it only seems to let me draw at best with other ACU. Even though I scout as much as possible, it's still hard to pick up if my opponent is going for gun on micro intensive maps like Open Palms or Syrtis major, and by the time I spam enough PD he has out money'ed me enough to put me at a big disadvantage.
What is the best course of action if I'm Aeon and a guncom shows up?
