The Main Problem I have with the Ahri nerfs(In my opinion)

I really don't have a problem with these nerfs to an extent(ahri main), she is in a very strong position right now. The problem I have with it is how short lived it is. I mean there is a lot of champs that most people consider op had a longer time and then they get for lack of a better term gutted. Imo when it comes to a champ being op they should have there time in the sun, but it being too short or too long sucks. Before the 5.2 patch i consider her in a good spot not op ,but not a bad champ I never understand why they made the change in the first place.
