Can we please have a webpage for champions and itemisation

Would be nice to have a webpage where I can click on any champion, choose what lvl I want to be, pick items and runes, then see what stats I would get. And also compare what kind of damage I would do vs another champion with a certain setup. Instead of doing alot of calculations and having this to go on: https://eune.leagueoflegends.com/en/game-info/items/ https://eune.leagueoflegends.com/en/game-info/champions/
