Fiora and Riven mains
I don't think that all Fiora, Riven players are the same - you shouldn't take my opinion personaly. I noticed that most of those champions mains I have met in the game were acting pretty similiar and thats it.
Actualy Riven isn't that strong atm, but then she was, quit often I would notice that her mains would complain if someone kicks theyr ass in the lane, that the champion they play against is op, etc...
The actual chat. I'm Khazix
Fiora: q 400 demage, khazix needs nerf
khazix: khazix is already nerfed and is hard to be useful with
Fiora: not enought
Khazix: look at his win rate
Fiora: so? riven has low win rate to
Khazix: .......................
For people who don't know why Riven has low win rate - shes very intense mechanicaly and is harder to learn then an average champion. People who have played more games with her, have significantly higher win rate.
