Mandatory online IQ test when buying Yasuo in League of Legends
Personally, I'm not a very good LoL player. But people playing this specific champ and his brother are either amazing or they are terrible, but never in my life did I see a Yasuo with a 1/10 score write "sorry team, my bad" in chat. I hear it's not just in silver and bronze, 90 percent of people playing this champ are like this. They basically int for the entirety of the early game, and then in the late game, since they are still playing Yasuo, ofc they get some kills, which makes their ego grow and think they actually did something. But they forget the fact that by feeding the midlaner and the jungler they destroyed every other teammate.
I know not all of them are like that, but some kind of sanity check or an IQ test should be required. If not that, at least make some kind of tutorial that you have to go through once you buy Yasuo (even Yone, but he isn't that much of a problem yet). I know it makes no sense to make a special tutorial for only one champion, but it also makes no sense that a single champion has more player base than the last 50 least played champions combined.
Ofc, I know that by now. Everyone who plays Yasuo already bought him, but then you could make it so that the tutorial/IQ test/sanity test is done if the champion is amongs the 3 champions with most mastery points of a single player. Maybe there would still be people that would play him randomly even if they don't main him, but by not maining him they actually know how he works, when he's weak, when he's strong, they aren't just TYPICAL Yasuo mains.
I know the odds of this petition actually working are slim to none, I just want to somehow voice my opinion about him in a way that gets you thinking about somehow educating his player base.
P.S. If someone suggests "Just ban him". You obviously don't know what a typical Yasuo main does when his teammate bans Yasuo. He doesn't just dodge, so his team can find a normal player, he stays and makes that game unbearable by going AP Zed, or Yuumi mid, or just goes to steal kills with something like Urgot and randomly dying afterwards.
