Conveniently ignoring the times that all of the first list were bad, or why so many of the other list are kept bad.
Was terrible this season until Conquerer existed. Months of being bad even in low ELO, where he's historically been strong.
Did this champion even exist for the first few months this season? Or for most of last season?
Dude didn't even exist for the past year until Stormrazor became a thing.
Been a lot of up and down. Vanished completely for the past couple months tho.
Completely ignoring the largest nerf he's gotten yet, where Riot removed one of his core items without compensation, are we?
Dude didn't even exist this year until crit changes. Still don't see him much, too.
Statistically still a bit weak. Also brand new. Hasn't had enough time for many changes yet.
Dude. Even this guy vanished in my games. Legit I have no idea where the fuck he went. Went from being all I saw to being less common than Ryze.
What buffs, though?
Vayne hasn't been useful at all this season. Even the buff she got still did nothing to make her be picked.
Wasn't the only buff he actually got this season done when he was at 42% winrate?
Dude hasn't been buffed this season, ignoring the compensation one.
(Also, for all assassins above, Domination nerfs are a thing).
And...The others:
There's a reason Azir isn't allowed to be strong anywhere. He's oppressive as fuck in low tier and broken enough that even Flex Tape can't fix him in high tier whenever he's allowed to be viable.
Same issues as Azir, but on an AD champion instead of an AP one.
Riot has no idea what the fuck to do with Karma right now. Along the same lines as
, Riot's having a hard time figuring out if she's a support or a mage. She has way too much damage and too little utility for a support, and too much utility and too little damage for a mage. She can do half your health with a Q, but that's it then. No more combo to kill you with, but half your health on a Q is too much for a support. Karma'll be good once Riot figures out what direction to take, and then reworks half her kit.
Dude was busted as fuck last year. And still was this year, because E+R+Nimbus Cloak+Zhonya's means you're incapable of avoiding his ult no matter who you are. Kennen needs a VGU before he's allowed to be viable again, because there's legit no counterplay to him if he is viable.
Not quite sure why she's not good right now. Probably the same issues as Azir, but to a lesser extent: Oppressive in low-tier, too useful in coordinated play due to ult.
As someone who actually does play Mordekaiser, please do not buff him. There is no buff that can fix Morde's problems without breaking him. He's too weak to kiting, but as soon as you reduce that weakness enough to make him useful, he'll be busted beyond belief. Just...Wait for his VGU.
Not quite sure where this guy went, or why he hasn't been touched, honestly.
Still too strong in high tier. Not even that she's low-tier oppressive, just high-tier (especially coordinated) strengths are too high.
Generic oppressive champion who's historically been good for exactly two things: Pissing 9 people off at once because you picked Teemo, and making the game an effective 4v4, as you make both you and your opponent useless. Teemo needs to be left alone until his VGU comes around, and that's coming from a m6 Teemo.
Statcheck with extremely little counterplay. You either can outrun him, or you can out-stat him in combat, or you die. He's a lot like Mordekaiser, where if you fix his issues he'll be busted as fuck. VGU is coming soon for a reason.
Ziggs is bad because...Well...He's not. 50.74% winrate is fine. If Riot wants to buff him much more, they'd need to revert W demolishing towers so that they can buff him in other ways. Or they could just buff turret resistances, which would buff Ziggs indirectly by letting his W demolish be a bit more useful.
