Mini-Reworks
Sometimes a champion in the game is Overpowered, Underpowered or just a bit outdated. It's not enough to warrant a full on rework though and isn't enough to warrant putting them in the list for class updates. These, are mini-reworks and i think it's about time we brought up some of the champions likely to get them and some that have.
It was really simple, they moved his healing to his passive, his E got a completely new effect and it made him more up-to-date without fully reworking him. It also stopped the issue where he was absolutely broken upon release back when he was first released.
They basically did what they always should have, he should eat more, grow larger, become an actually monstrous trans-dimensional being instead of just, well a tanky alien from starcraft. (he still shouldn't have a silence though, no juggernaut should but i'm not a game designer.)
Now riot has stated that this is really the first time they did a mini-rework like this but that due to it's success certain champions are in line for them too. The main reason for many is simply, their broken, their way to strong if ever buffed and often way to weak if ever nerfed, they often have way to many tools and dominate in both solo que and pro play.
If i really have to explain why this champion is in line for a mini-rework, then uninstall league. Basically he's a lane bully, zone-control mage with AMAZING range, ridiculous damage, amazing scaling, one of the best dashes in the entire game and an ultimate that can and has won HUGE amounts of games on it's own. He scales hard like a marksman, teamfights like a mage and rules laning phase like a juggernaut(just without being tanky), it's actually insane when this guy is even remotely strong.
She's an EXTREMELY mobile ADC, most ADC's aren't very mobile, the most mobile ADC i can think of is Lucian because his dash has a reduce cooldown mechanic, along with graves. But she also has a REALLY strong AOE engage with her support, ridiculous damage and a very VERY powerful counter to smite making her a menace in pro play if she's ever strong. Her Rend ability is also an AMAZING laning tool for harrass and poke, making her a lane bully that scales better than almost anything else.
Another marksman, the issue with kindred is that she ganks really REALLY well early, or used to before jungle changes this season, she was basically able to do what lee sin can in the early game then outscale you in the late game. Again due to being a marksmen, her scaling with the items she get's, her constantly increasing damage that was current health damage, her amazingly safe jungle clear and her game-changing ultimate made her pretty much pick or ban for, well, years.
He simply breaks the game, yasuo's kit is overloaded with a lot of things it shouldn't have, there's a reason for this though. He was supposed to be a bot lane melee, the issue though is because of all the tools riot gave him to avoid harass against ranged champions and in general everything. He becomes a massive lane bully in solo lanes, who, like many other's, will outscale you in late game because he builds like a marksmen. Marksmen items and marksmen in general are supposed to scale into late game but the draw back on this for most is that they can't lane very well, making it possible to win against, say, Vayne before she get's strong enough to be useful. With yasuo though if he get a kill or two in lane the game for him can just go out of control due to his passives double crit chance giving him double the stats his items should give, making a back for yasuo where he has 1200 gold from a kill basically the same as having 3000 gold instead. He isn't ever strong in competitve play though but his kit has finally been recognized as overloaded and toxic so expect to see changes comming his way soon.
These champions have been mention in many comments, posts and talk from riot as needing improvements and in all these cases they were also stated as being thought of for mini reworks. I'm actually excited for most, if not all of these because kindred is one of my all time favorite champions and i'm kind of tired of her being pick or ban, or if not those they're simply to under powered to play. Also sick of yasuo hate, even though i despise his existence, i like his design it was just executed poorly in my opinion. Kalista and azir fall into the same catagory as yasuo to me as well.
Edit: basically as a note to self for riot, don't make champions that are bully's early and outscale you late, every champion that does that has been historically broken and needed fixing or been flat out hated and constantly banned.
