I think Stealth should be removed from the game until it is Healthy, Change my mind
There are exceptions to this case, but overall I believe Stealth Mechanics should be removed from the game until Riot figures out a way to make it healthy. The following is all my opinion and if you disagree feel free to comment but let us be civil. I am listing champions stealth by priority to me on how toxic these abilities and mechanics are of their stealth. Either way we should find balance to stealth mechanics before making anymore champs with stealth!
Akali - I know she is getting a rework, but lets talk about her current and possible future stealth. Her W is absolutely toxic and makes trading with her a nightmare as 1 she doesnt have Mana so all she has to do is drop that get an insane movement speed and blink all in 1 package. Idk how many champions get so many things in 1 ability (usually you might just get a passive ability), but she gets so many active abilities just from a W which is 8 seconds of stealth! Then she can proceed to attack you with almost 0 counterplay as she will just be invisible and you cannot react with any auto attacks and targeted abilities. Do not even get me started on her new possible "TRUE STEALTH" Cannot even be seen by turrets why have turrets at all and I am starting to wonder if Riot is trying to get rid of turrets at this point?
Rengar - so to give you some context I took a break from the game for 15 months from March 2017 - June 2018 and to see Rengar reverted to this disgusting state is just unbelievable. It does not matter how far behind he is as he can instantly pop any "squishy" target. This shouldn't be a thing like ever no one has fun in a game where someone comes out of no where and just 100-0 you in a second.
Vayne - I started my League of Legends "career" as an ADC main (Caitlyn end of Season 2) and I have always despised this champion. I think one of the worst things about Stealth is the ability to go in and out of it quickly as it makes it feel like your being outplayed by a mechanic and not by skill. Trying to guess where a champion is because they keep going in and out of stealth is just a terrible and un-fun experience.
Talon - He is a bit Over tuned, but I will say his stealth is honestly not that bad compared to others his damage however is out of control.
Wukong - Stealth is not his issue again just like talon his damage is a bit out of control
Shaco - I mean a good Shaco is one of the biggest pain in the asses, but a bad shaco is just terrible and useless so it shows there is some skill needed here.
Kha ZIx - I do not think his stealh has ever been a problem on him (other than when it gave him insane Damage reduction) so I think his stealth has a decent balance to it.
Twitch - Because of the adc's being nerfed it is hard to fuly gauge, but his stealth is not terrible and its timed, probably one of the better of all the stealths and he cannot go in and out of stealth when he feels like it (talking about you Akali).
Evelyn - I cannot comment on as I am not aware of her new abilites as the old Eve I was use to was always stealth.
Kai Sa - Does she need the stealth definitely not, but its not the worst thing to exist in League of Legends.
Leblanc and Teemo - These champs Stealth are situational so not really a huge issue.
