This guy is pulling off some insane control of four warriors? It was a while ago but It looks mesmerizing, I get that it's sped up abit but can someone explain what's going on here? is it really just interact with target?

Yup, that's what it looks like.

Agreed. My SM runs look pretty similar when I get ranged aggro.
