So, op champions and trashed champions

So, I thought about it a bit and found out(which most people allready have): that when putting a champ that's say, average or even on the weak side next to a super op champion, it makes it seem like the average champion(one that doesn't need buffs) will need buffs, instead of nerfing the op champ, they buff the champ that didn't need any I thought of it the other day, so i'm not sure if this is exactly what i was thinking. your thoughts?
