Me myself loves Yasuo
but i think only one champion with a sword and wind abilities gets boring why not make atleast 2 or 1 more champion a girl to be exact with a sword with Fire,Water or Earth Abilities i think a girl with a Samurai Sword whooping yasuo's ass in mid lane would be cool, and a lot likes yasuo but if he doesnt get banned he gets picked, so having this new samurai girl would be cool to pick if facing yasuo or if he's banned
Let me put some examples of Elements.
Ice
and 
Nature
Curse, Decay, and/or Darkness
Earth
Fire
Wind
Lightning
Darkness
Balance and/or Light

there are more elemental champs than I listed, and if you think about, you'll realize there are a lot of champs with elements that Riot made, so they're trying to make some variety by adding champs like 
oh by the way. Sadly, I doubt there will be more swordsman characters, as there are Yi, Garen, Yas, Shen, and Riven.
I made a elementalist champion a long time ago, she didnt use a sword or anything but she does use fire, water, and lightning spells, unlike any other champ in the game as all the mages only ever use one element. https://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/yNpyXmFm-champion-concept-res-utsuro-the-ultimate-magus-wip
