Ahri is way more broken then all those Vaynes, Yasuos, Twitches etc etc you are talking about.
Ahri is a pure cancer cheat champion. I myself got 88% win ratio with her. Every time i pick her it`s like cheating. Pure cancer broken champion. Counters EVERYTHING. Only Yasuo can make some little problems but in comparation with her, he is 0 in teamfight. Ahri is, by billions, the most retarded and broken thing that is still unchanged after all this time.
