List of champions that Riot is going to rework sooner or later
While everyone knows about the big names in the rework bin of Riot, Yorick, Taric, Urgot, I thought I'd make a list of the champions that Riot's going to eventually rework at some point even though they currently aren't nearly as in need of one as those three.
Not a surprising one for most people. Aatrox suffers from a lot of issues but his biggest ones are that his kit very much a generic fighter one that doesn't combine together to make a particularly unique playstyle and that he doesn't deliver on the kind of fantasy his lore implies you'd get.
Also probably not surprising. Akali's issues are that she's a very binary champion where if she's good or ahead in a game then she's oppressive because of how simple her kit is and because of how hard it is to get away from her. The only things in her kit that make her really stand apart from others is her passive and her shroud. She mostly just doesn't provide a lot of interesting gameplay.
Fiddlesticks doesn't have anything that makes him seem like someone to be reworked on first glance, his gameplay is unique and he's not troublesome to balance. His problem is mobility creep. He's a very slow champion that's main damage source requires the enemy to stay within range of him to let him drain their health. His kit probably won't need a change like Poppy or Sion's as he's got things to bring to a team and he doesn't have toxic aspects to his kit. His issue is just that he needs to be modernized to be able to keep up with how the game works now.

This one also is probably not surprising. Galio is one of the oldest champions and is in need of a story and gameplay update. While he's certainly strong right now when played by someone that understands when to pick him and how to use him, his kit needs to be tightened up and given more focus. He's got crippling mana costs and his kit needs to be given a more defined focus on what he's supposed to be picked for in a teamcomp aside from being good against heavy magic damage teams because of his passive.

Irelia and Xin I am putting together here as they have similar problems. Like Aatrox, actually even more so than Aatrox, they have kits that are very generic fighter type of kits. Xin actually has potential for interesting gameplay due to his ult and passive, but his challenge passive could be redone to be more interesting for both him and his opponent. Irelia is probably worse because so much of her kit is just a generic ball of stats and Riot has said they wish they could do more with her blades.

Tryn is a case where he's frustrating to deal with when he's good and completely ignorable when he's not. His crit passive for early level cheese and his main strategy of just splitpushing all game and then running away if the enemy team comes to stop him or just killing the one person they send after him, along with his ultimate allowing him to duel almost anyone, make him frustrating to deal with. However, Tryn also typically doesn't provide much for his team in a teamfight which is why he's used for this kind of strategy.

While Swain offers a unique kit and he's not unbalanced, chances are that Riot would like to rework him at some point so that his title of Master Tactician factors more into his kit. As he is currently, his kit doesn't take that much thought to use, it's mostly just a matter of judging if an enemy is close enough for you to get all of your spells off on them.
Volibear also somewhat suffers from generic bruiser problems. His kit is also very binary in what it's capable of as it's designed basically just for, "Run in and hit the enemy a bunch" I don't think it would be too difficult to take the abilities he already has though and work with them to create a kit that's more unique and delivers on the idea of an unstoppable bear that rampages through the enemy lines.
So those are the champions I see as being up for reworks by Riot sooner or later. Keep in mind that just because I say these champs are going to be reworked does not mean that I think they're bad champions or that I think less of someone for playing one of them. I'm just looking at this from how Riot probably sees things. So agree, disagree, or add who else you think is up for a rework in the near future.
is probably somewhere on their radar, if not for something big then at least a cleanup of his kit. He's very bursty and tanky, but his abilities aren't super refined or distinct outside his ult. I love playing him but I'm pretty sure they think he needs work eventually.
is probably on the list somewhere out there. His failure case is bad, but his success case is hella strong which makes him overly binary as a champ.
They've said they want to do work on her for a long time, but since she's in a decent spot right now, she's probably off the short list.
They mentioned somewhere that they want to do a much bigger scale rework at some point in the distant future to take him more in the "freak of science" direction rather than the "Purple hulk" direction he has now. I don't know what that entails, but it sounds cool.
Yeah. Her. She's managed to hide from a rework for a really, really, really long time. She's skirted in and out of the spotlight and has drawn attention but isn't currently slated for work in the foreseeable future.
They're just scared of backlash. They also aren't quite sure what about Lee makes him unique, so he's been given a pass. How convenient...
They just about finished a "rework" for him (poor bloke), but they said several times that they want to do a sion tier relaunch in the not-so-near future.
They don't seem to have any plans for him, but they've acknowledged that his laning is a problem, so maybe he's slated way far down the list?
No matter how strong he is currently, Rammus kit is starting to show its age pretty badly. It is relatively passive and relies too heavily on the actions of his enemies.
As long as he can still insta-burst a champ, he's going to need work. Stealth plus some of the highest burst in the game (when not abysmally far behind) is inherently toxic, and his last rework fixed almost none of his real issues.
I'm pretty sure we can agree that his last rework failed badly. He is still either hella OP, or nearly unplayable, and he is still a lane bully with a hyper scaling late game.
Needs work. They gave him some love in 5.22 with the clone adjustments and miss chance change, but he needs a larger more comprehensive overhaul to really hone in on his mind game centric assassin work without being quite so frustrating for the enemy team.
He used to be satan, now he's just that annoying guy who pesters you while you farm. He needs a lot of love and a clear direction for what his kit is supposed to be about.
Kind of obvious. OP or not OP, he has an annoying overloaded kit which everyone here knows enough about that I don't have to go into detail.
Still doesn't feel at all like a legitimate "time mage". The extent of his time mechanics are cheesy puns (seriously, the best you've got for an immortal temporal wizard is "time bomb"?) and dull gameplay that basically revolves around "run fast, drop bombs for a stun, keep people from dying". He is extremely bland and really a huge, huge missed opportunity (I'm still dumbfounded that they would create a whole new time travel champion before giving Zilean the rework he deserves).
She's kind of stuck in between being a support, a classice utility mage, and a minionmancer. Her passive is bad, and her kit needs to prioritize on a few select design aspects so that she feels more cohesive to play as. If you want to push utility mage, emphasize her seed vision and CC capabilities. If you want her to be a minionmancer, improve her capabilities to interact with her plants in a meaningful way outside "use Q for this type of plant and E for this type of plant!" She has a lot of good stuff going on but lacks the focus to really pull it off convincingly.
riot comment they might be the next 2 juggernuat reworks at some point.
I feel like one will happen with his VU whenever... that is... his 4 stances will probably stay, but I'd expect changes to them.
Riot **hates **his design, one designer called him the single largest mistake they ever released, so it will happen.
Been confirmed since he's not very ninja-ish.
IS HE A TANK OR A JUGGERNAUT ???
WHERE IS WARWICK, HE IS THE WORST JUNGLER IN THE GAME BECAUSE HE HAS NO CC AT ALL ! SINCE WHEN
