Something bugging me about Mecha Rengar

I can't be the only one feeling this, but Mecha Rengar looks kinda retarded. Wait wait dont get me wrong the skin is sick, its just.. this one part https://gyazo.com/a072d4a7099e62f26d2e250e626b2449

Hard to tell in that snapshot, but when you play with mecha rengar you know the feel. The blade on his hand looks almost flimsy, and when he walks it llooks like a duck the way the blade stays stationary but his body moves. I feel like if the blade was rotated 90 degrees, mecha rengar would look much more intimidating and cool than having it flat to the viewer,
