New new champion/rework balancing rule

Should there be a rule at Riot that says they aren't allowed to touch this champions numbers or mechanics until 2 patches have past so like a month so that way people can settle into the new champion's existence? I mean like nothing at all unless it's a small hotfix or they are complete garbage like Ornn release numbers. Also you can't play them in Ranked until you play X games with them like a mission or a patch passes. Gotta cover that basis since I know a lot of you don't like that.
