Its not a free one hit kill every few seconds. Have you ever used it? It takes 3 seconds to charge after sprinting, only last 4-5 seconds, and can only be used once per sprint. Its very situational. You cant turn corners with speed at all, so unless theyre straight ahead of you within those few seconds your shoulder charge is ready, its worthless. And we have shoulder charge over the other two classes because were the only class without blink.
