Presumably since hes highly mobile with high damage and life steal. I haven’t played though so its just my 2c.

Because when he gets in range he eats up hp like crazy. To counter that he can only take so much damage before dying. Besides you can tell by the way he’s built he won’t take as much punishment as say Montana or Boldur. If it wasn’t for that armor, he looks ready to snap if hit with the force of a feather.
