Generic phantoms are incredibly fun to fly, and feel balanced with shooting every other turn. Named phantoms with acd are the game breakers.
I'm quite liking the flux we're in now, the last 2 store championships I've been to have been won by double decimator and a deciphantom list.
I see wave 6 (Autothruster edition) as being a nice counter to fat Han, but not so great against decimators packing Vader.
