Biggest Art to Lore inconsistencies?

Times where the art of a champion is inaccurate to their lore counter parts.

The biggest one I can think of is Jhin having an actual ball-joint mechanized robot arm in-game and in his splash art despite him having all 4 limbs in the lore. The plating on his arm is simply supposed to protect from the recoil of his weapon but I think half of the art team misinterpreted it. Another one I can think of is Orianna having her wind-up key in game and in splash arts despite the key being removed in her lore.

I think there might be something wonky with Janna's tattoos as well, but I can't think of it off the top of my head.
