I know Garen just got a new skin, but hear me out.
I just had a cool idea for a Garen skin. Basically it'd be a robot skin for Garen, maybe make it part of the mecha or project skin lines. But the main gimmick of the skin is Garen's E spin would make only his arms or upper body spin, and the rest of his body would be normal (like spinning on an axis but like he still walks straight forward. Idk just a thought I had.
