Pharaoh Nidalee
As a 
main, I have to say some of her skins look pretty outdated. I am aware that other champions and skins are in need of a more urgent visual update but hey I can be biased, right? xD
Particularly pointing at Pharaoh Nidalee here. The cat form textures are so awful it makes me not want to use that skin, which is sad :c
IMO most of her other skins look pretty good but it would be hella cool if Snow Bunny Nidalee turned her into a snow leopard instead of a white striped cougar ;) (just add spots!)
