What champs need reworks?

I've been wondering what champs need to be reworks, and the main champ that I say needs a rework is . I think that he needs one because he has been the same since I started playing league, which was back in about Season 3 or 4. I want him to get a rework because he is such a basic champ, but at the same time I don't because if he gets a rework and I don't like his playstyle afterwards, then I will have 3 skins no longer being used (Loch Ness , Jurassic , and Battlecast Prime ). I also want to know what champs you guys think need reworks.
