Boneclaw Shyvana
I get that it's a bigger problem dealing with the identity and aesthetic feel of a champion than that of an old skin, but really riot? Someone hears "Boneclaw Shyvana" and the first thing that they think of is playing as a giant skeleton dragon rampaging around, not a white and purple ripoff. The concept of Boneclaw Shyvana has so much more potential to it, and it's all wasted. The art barely shows the dragon anyway, someone not paying attention to the splash gets in game, farms to six and is completely disappointed when they ult (me).
Maybe a different identity from the Jurassic skins is something that matters, but it's not like Boneclaw is a skin line. I doubt Shyvana is getting a VU or a VGU, but who knows. No one saw the Shen rework coming...
TL;DR Boneclaw Shyvana should actually be a bone dragon, not a dragon wearing bones.
