Everyone is swapping armies left and right because of the changes. The meta has certainly changed, that's absolutely true. I play Ad Mech, and they seem to have been neutered. But you know what? Fuck it. I'm going to stick with them because I still think they're cool. I fell into the trap in 7th of not using things because they weren't "good." Fuck that. That's nonsense. Not shelving my army just because it's not as good as it used to be. When I started playing AoS, I chose an army I liked the look and flavor of, not the one that was strongest.
