Remember that this is a heavy underdog test, not mid or top team. My Mean Machine tactic got butchered here as well, as it's not an underdog tactic
I tested Killerbee with both Burnley and Deportivo. It's not a top team tactic although the formation would suggest otherwise. I achieved 7th with Burnley and 3rd with Deportivo first season. Hence why I'm rather surprised to see it falter so badly here.
