i enjoy playing against riven mains some are nice ppl and some are not
From personal experience, I've found Riven, Fizz and Katarina mains to be the most toxic at Lower Elo play. Their kits are extremely forgiving, either having no resource requirements, or extremely safe engages/disengages, and while Riven mains will scream day and night about how hard it is to balance passive stacking and Auto-cancelling, I just don't really see it. Their scaling is super-forgiving, and no matter how hard you shut them down early game, lategame a Riven/fizz/Kata can still pop in, shit out a Quadrakill and hop skip and jump back out.
Also, AD-scaling shields are cancerous.
It's actually kind of a shame to think that RaptorKarr is the only nice Riven main out there...
Rivens have put a bad title on themselves.
While I think Riven is a very faceroll champion and I dislike that... she can also be counted to yolo in like an idiot and get herself killed then ragequit the game pretty often. So in a sense, she's one of the most fun champs in the game to play against, because NOTHING feels as good as stomping a Riven out.
