The problem is not ahri, the problem is glacial augment
After buffing it over 3 times it just made it too reliable, now champs like ahri (even sion/urgot sometimes) can just keep applying it over and over to make their kits point and click basically (urgot aas then gets a free Q in, ahri AAs then her whole kit might aswell become point and click, etc).
Basically it needs to be reworked, rune is just not used enough and is only ever useable when its overtuned like it is now.
Also time warp tonic is ridiculously broken with dark seal (s) and corrupting pot, you'll see every top/mid abusing this setup in worlds.
