Riot likes to take things that aren't a problem and make them a problem.
The entire reason you nerfed darius ult was because you were tired of having top laners kill with their ult and come back and have it up again.
Yeah you only did that to riven and darius, and riven still has her ult coming to lane.
You buffed exhaust, so not just autoattackers are fucked, EVERYONE is fucked.
I don't remember cass being a problem, she wasn't UP or OP, but you MADE her a problem by breaking her. Congratulations, she is now unfun to play as AND against.
Assassin's weren't a problem, then you had to break them and give them no counterplay.
ADC's weren't a problem, then you had to break them and give them no counterplay.
Tank's were a problem, but you overnerfed them. Extremely.
Anything else I missed that they took from not being a problem and made them a problem?
