There's nothing wrong with Ahri...she's perfectly fine atm...played her yesterday twice...had no issues, did well both times...she feels pretty stable atm...some are even arguing she's overpowered after that mini-rework because of her insane movement speed buff off her Q.
Akali...yea...she just got turned into poo. Even worse...only reason why was because of the lowest common denominator people refusing to by a frickin' pink ward. She was anything but overpowered in the hands of people and vs people who actually knew what they were doing.
I do not understand why people are always whining about Lee Sin. He's strong early...but then falls off to garbage in the late game where all you can do is build tank. Is he annoying...yea...is he overpowered?...not even close. And I don't even play him...so there's definitely no favoritism in my opinion. Currently Jarvan is another level above Lee Sin in strength...people just cry because of Lee Sin's mobility. People picking Lee Sin...comp for it...that simple. Hello Lee...meet Morg.
