Riot doesn't know what they're doing when it comes to reworks.
Riot's main job is to take care of the players that are upset with certain things in the game so they can change it and make things "better". I say this because what company would want bad ratings from its players? But in the way Riot does it is ridiculous to people that love the way a champion is. Champion mains can be fine with a nerf here and there, but never too excited with reworks and that's just the way it is. Sometimes it can be understandable, other times unreasonable.
Riot has completely trashed (and by this I mean completely ruined the champion from what it used to be, and the value and pride the mains had in it) several reworks including Sion, Mordekaiser, I don't even have to see what they're doing with Rengar other than what they told us that they're gonna trash him to (still gonna try to be hopeful, idk why or how though). They still don't know what to do with Ryze obviously, he's on his 3rd rework for crying out loud. I have no doubt that down the line in the future a bunch of players are gonna be upset with him because he can still do a whole bunch of damage, sometimes even one shot people, as well as being pretty damn tanky, only now he can offer more utility to his team with his new ult.
Riot: "Rengar will still be an assassin, but tankier and with less damage." ASSASSINS ARE NOT TANKS RIOT. THE WHOLE DAMN POINT OF AN ASSASSIN IS TO HAVE DAMAGE. The whole damn reason Rengar is as op as he is, is because of items, not entirely his kit. Crit Rengar can chunk 50% hp with an auto attack, then you have things like Herold buff to add on top of it WHICH LASTS 20 DAMN MINUTES. He has lots of counter play from cc, tanks, pink wards, vision in general, Lee sin, twisted fate, oracles lens, sweeper, ignite and many more. But the point is once he gets ahead, not him in general.
Static Shiv also has a ton of damage because of it's passive allowing to crit for even more damage. Allowing 100% crit in the game will let anyone whole builds it completely crap on someone then use their victim's upper lip to wipe their ass.

They don't know how to rework champions in a way that still keeps who they are (FOR EXAMPLE SION AND MORDEKAISER) unless we take it to the lore where they try to keep their theme amongst their new kits that only the people who hated the champion before will like. Except Mordekaiser, no one likes him now. But also not knowing how to keep the champion that their mains know and love at a balance to what the people who don't like them and want them changed. I know it's an incredibly tough job to do, and I thank you for everything you try to do for us.
What do I think they should do? I can't tell them what to do, it's not like they would listen to anyone in the first place unless a post has 500+ upvotes. They put and keep everything at high ranked and competitive opinion, gameplay, history and outcomes of games, stats, and countless other statistics up there.
But what I suggest to them for their future reworks is to try to make a page specifically for the mains on a champion that they're about to rework. They can already make up their mind that a champion will be reworked or not, but at least look at the mains opinions, suggestions and ideas. They already get enough complaints (which is why the rework is probably going to happen in the first place) from people who don't main the champion. So now that those people get their way to have it reworked, listen to the mains so you don't destroy the champion and make them find a new main. You don't know how sad and frustrating it actually is to have to do that.
I apologize for the rant. This post isn't for any champion specifically, even my Rengar. I don't know about anyone else, but Riot seems to keep in mind what a expert main can do with a champion, not what they think about their champion. I just ask they listen to both parties (mains and people complaining who aren't mains of the champion) equally and make it a little more fair by adding a page for the champion mains for future reworks. I'm certainly no expert, heck I'm only gold V. But I am a main, I don't endorse the idea that someone's rank shows what a main of any champion is capable of doing with them. You never know.
Riot all I ask is that you be more open-minded. Please and thank you.
