Some champions literally don't have counterplays. Which is why they are played in high elo. Do you know a counter vs qiyana? There is no such this. "don't go near walls" - her ult literally throws you into a wall even if you are in the middle of the lane, test it if you don't believe. She doesn't have skillsshots, since you can hit your q while you are on top of your enemy. Her kit is just too good atm.
The same goes for Sylas. His kit has counterplays, but they are not that easy to use since his e is very easy to hit. Actually, forget about it, I like this champion. Qiyanna too. I might actually play them.
There should be more counterpicks against Yasuo, so that he isn't banned all the time and then it would be ok. Also Morde R should be changed, it is too good vs supports. They can't do anything.
I have nothing against other champions tho. They might be slightly overpowered (jinx) or massively overpowered (pantheon), but I can manage with that .
Lastly, I actually think that the game is ok, but it would be better if damage was lower. Overall. Atm everybody can kill anybody with one combo. I had more fun in seasons with more strategy in the game. I really miss them. Still consider the game ok, but I have that feeling that without so much damage, this game would be a lot better.
Also, I am tired of that too. People should do the same we (Shaco mains) did, which is "talk with Riot". A calm and civil discussion over important topics can change the game. Not yelling, yelling won't do shit.
