You're the first person I heard say this in a long time. Let's just say I don't agree. Turrets still dominate and that's the point of this thread.If the meta it's healthy, there IS NO "Best Build." There are many strong build archetypes that all interact in interesting ways. I think we currently have the healthiest meta since Wave 3.
Turrets will always be good, but maybe our Atlanta meta is just different. We're seeing a lot of Y wings and HWKs but falcons and Decimators have all but disappeared, maybe one per tournament. And X wings have made a comeback now that turrets have backed off and the new phantom rules.
