You act like I haven't seen Yasuo's rip people apart at every stage of the game before. The reason I stopped spending a ban on him is because I swapped to playing
. Since Yasuo can only windwall one of my spells now, I'm able to actually play around him. A good Yasuo still leaves extremely little room to counterplay him, even if you do manage to counterpick him, you should know that.
Yasuo and LeBlanc are the only ones on that list that are consistent bans.
is a new champion, she'll stop being banned after she's been out a few patches.
and
are Junglers that are currently strong, they'll be swapped out when the meta shifts. Same goes for
in her role as ADC.
is mostly banned when she's strong and popular, just like
or any other assassin.
getting banned is a joke, on par with banning Urgot.
and
also rarely pull bans, most commonly by players who have recently had a bad experience against them.
Yasuo has remained a constant ban (unless other priority bans shove him out) because of how hard he counters massive sections of the champion pool. His win rate is on par with LeBlanc's at 49.56%, he's certainly not weak.
It's perfectly right to ban champions you find annoying to play against or can't play against effectively. Why do you think MF Support got banned at Worlds? It was annoying, effective, and SKT didn't have a good counter to it.
If you don't like having your champion banned, go play Blind Pick or pick a less frustrating champion.
