The counter for gorge rush is not "waste all ur res on shotguns"
Yes, you need shotguns to counter a gorge rush, but even more importantly you need an obs and the ability to beacon. Gorge rushes depend on the fact that gorges in MS don't have to fight a whole team all at once, they fight marines as they come along in small groups falling back to defend. Please stop doing lame ish and build my damn obs.
