he's not "good" in low elo
he's a fucking nightmare his toxic kit makes him extremely difficult to 1v1 and kill him, mind you talking about a decent yasuo here, doesnt matter how good you are at your champ or how much you are fed a decent yasuo will somehow manage to emerge victorious out of every duel with so little health
him getting fed makes him exponentionally stronger so his good dueling potential elavates from impossible to lose a 1v1 to impossible to lose a 1vs2 to impossible to lose a 1vs3 etc.. that's just how strong this fucking shit champ is
and somehow it's so easy for him to get fed every fucking game it's like all lanes are designed to give yasuo kills on a silver plate
he leaves his lane 0/2 returns to lane 2/2 every fucking time late game he's 13/2 so losing lane doesnt even matter cause nobody ever will outscale his bullshit fucking damage
and dont assume the enemy yasuo will always be carrying 4 idiots it's more than likely despite it being "low elo" (yeah flashnews a high portion of low elo's are not that retarded) his team will have his back once he gets fed for the rest of the game making an even more near impossible to duel character harder to take down
for a melee his Q range is fucking obnoxious he can walk up to you q you under turret and not get turret aggro
you can't punish him for missing his ult since he cant fucking miss it you can't bait his ult which is his biggest strength since it's always available (he can even land it when he miss his q because yasuo knock up from teammate magic)
tons of free damage for no reason upon building even half a crit items (i wish i was exaggerating)
his ult ignores half your armor (balanced)
his ult is a nuke with hard cc that can not be cleansed or qss'd (balanced)
his passive give him tons of damage on auto attacks so he melts towers faster than -whatever many stacks- nasus
but yasuo is squishy right? yeah how many fucking times he runs away with so little health because his passive shield saved him i'll admit if they remove that part of his passive he will be garbage but he'll be balanced =easier to take down and kill at every stage of the game
because he's so fucking tanky for the damage he offers
tl;dr yasuo will always get fed somehow and 1v9 9/10 of times and he's so fucking unstoppable and bullshit it's becoming an annoying meme
also what? how is yasuo not good in high elo? isnt yassuo a challenger and he's doing so well in his elo as well? because i highly doubt yasuo is the kind of champ that will be stopped by "outskilling" him he's literally the definition of cancer and "i'll outplay you no matter what" that's why people fucking hate him
maybe high elo dont have many good yasuo mains not that yasuo sucks in high elo all yasuo mains lurk in low elo to torture "bad" players because all yasuo players are obviously sadists
