I thought Riven was super strong at highest elos?
Poppy nerfs are only a slight tap at what is the true problem with her. Same with Lee, his ults damage was not why he is so oppressive, it was merely another tick on the list of things that make him a superior champion. There are a multitude of other issues with Lee Sin, Hecarim and Vi also have a ton of balance issues.
Syndra still does an immense amount of damage if you are skilled with her, or so I've been told.
People say ADC's are weak, but then Cait E+AA's me for 80% of my life while lifestealing any amount of damage I can do. I mean maybe the other ADC's are weak but it seems like Cait, Ez, Jhin, and Vayne are all doing just fine. Maybe we will be seeing Draven up there too?
Ap Ziggs is a menace at low elos... people are so bad with him I am banning him to keep him off my team. But in all seriousness he is just another issue that needs looking at in bot lane.
