Instead of nerfing for champs for pro play and hoping they're balanced for the rest of us

Why don't you try nerfing champs for the player base and hoping they're balanced for pro play? I mean, they have 5 bans so if a champ (Camille) is just OP, they can always just ban them out and it would make the other 99.99% of players not have to deal with them. For example, let's say Aatrox was OP because of his Q in pro play, but because of his W in regular play. Try nerfing his W instead of his Q and seeing if that fixes him for both instead of nerfing his Q and hoping that fixes him for both. Just my two cents.
