Ragnar/Aunshi Combo needs a nerf

Ragnar, Aun'shi is unbelievably broken, I'm tired of loosing to a no skill, brain-dead , high movement, low risk, extremely punishing deck. I can't use anyone but the mentioned characters with melee focus it's insane. Why haven't this been nerf??? It's exhausting loosing to the same deck and nothing has been done about it?
