Why is NC winning? Like everyone else said, the equipment. JH obviously is in a different class compared to MCG and lasher, Vanguard is way too powerful, and IMO the scattercannon is the best.
CR5's might as well be typing in a different language for all the people that listen to them. And most of them are idiots too. I've seen only a handful of smart CR5's on Emerald, all empires included. They make no big difference, especially in big zerg battles (it's called a zerg for a reason, just mindlessly running in to death
).
