@IronStylus, @VU Team. What 's your thoughts on Amumu? What would his VU try to do?

Thinking about what his VU might be like, it seems to me like he'd be a hard nut to crack.

He probably pretty far down the list, considering he's both fairly cartoony and iconic, so the cost of letting him be for a while isn't huge. But entertaining the thought of updating him, what'd you even do with him? It seems to me all the issues with his visuals are really hard problems.

• He is supposed to be a child, not a yordle, but could changing his proportions and shrinking his huge head ruin his silhouette and readability? Would Annie-proportions make his face hard to read? Would he look too dainty, even more so without the big head? He is always represented very cartoonily and exaggerated; is there even a way to translate his visuals to a style that works next to other champions in the game? It's hard to buy that he is human putting him next to Annie, given his hugely distorted proportions.
• He's a tank, but he doesn't really look like one. How do you make a wrapped-up dainty child clearly read as a tank character? Does he block attacks with a "bandage-shield", or a VFX barrier, or what? What's there to make it obvious to an uninformed party that he is a tank?
• There's very little to work with visually; he's just a green blob. Could one add clothing, "accessories" or new materials? New shapes? Are his visuals too iconic for drastic changes like that?

Have you given this any though, how would you solve these problems? Do you have any internal concepts or ideas for him at all?
