Please, please add win:loss ratios on specific champions in match history

I think it'd be great if Riot added a win to loss ratio in the match history on the web for champions. You see which champions you're good at and which ones you need improving! Sometimes, I wonder which champion I do best at certain roles, or ones I need to practice on. I would also appreciate that you would add separate ones for ranked, normals, e.t.c. but one overall (Ranked + Normals). I know many websites have champion stats, such as your KDA and sometimes your win:loss ratios (only ranked), but it would be convenient if it was at the match history on League itself since it has all the matches played by the player. :^) that is all first time using boards; has no idea where to put recommendation in boards
