Why assume 5 second cooldown when that’s only for auto-oc that I want removed?
These stats also don’t really showcase the reality that a gun ACU has continuous free value because the only time your calculation comes into play is if you have so many units that you can swarm ACU+its units. Most of the time, there is a very high margin of error that makes that infeasible and so ACUs get free value shooting at stuff. The point of the gun change is to make the margin of error tighter for keeping your ACU in an aggressive position.
