What I Would Like to see from the Evelynn Rework
Evelynn is a champion who has been attracting reworks since beta, and she's due for another one coming next year. I don't have a concept for the rework, but I do have what I would like to see her gain, what I would like to see her lose, and what I would like to see her retain. Retain Stealth I want to see her keep some mechanic of stealth in her kit. Maybe some heavily modified version of it that's easier to balance, but something to hide her from the enemy's sight. Her niche is her sneakiness, so she should certainly keep stealth in some form. E Her E is a very good ability that I would like to see mostly remain untouched when she transfers over. Camp Clear Evelynn is usually played as a jungler, so I would like to see her keep something by way of a fast clear or at least some sustain replacing the sustained damage in her kit.
Gain Burst Evelynn certainly needs more burst. Though labeled as an assassin, she's forced into a more fighter/juggernaut type of build because she just doesn't have the burst to get the job done. Gap Closer/Escape I want to see Evelynn get some type of hard dash ability. The movement speed from her W instead of a hard gap closer combined with the lack of burst is what forces her to become a pseudo-juggernaut. She certainly needs some hard gap closer to make her feel more assassin-like and give her some more flashy outplays. A New Ultimate Her ultimate is, honestly, useless on an assassin. It deals % current health damage in an area of effect, slows, and gives a shield. This is an ability that would certainly fit more on a tank or fighter than an assassin. Visual Update Just a bit of a thing not kit related, I would like to see Evelynn get new visuals or at least a tune-up. And please make her have a new outfit that isn't her nearly-naked one. PLEASE.
Lose Passive Stealth Her stealth passive is, honestly, pretty broken. It's the reason why she can't have everything she needs as an assassin. While I would like to see her keep the stealth, she certainly needs a new passive that can have balance that isn't "Make this assassin have no burst." Q Hate Spike is an ability that has been on her kit since the beginning, but it doesn't really fit on an assassin's kit. A low cooldown, low damage (sustained damage) ability again fits more on a fighter instead of an assassin. It might not need a full rework, maybe just a tune-up to give it more damage at the cost of a longer cooldown, but it needs something to make it into a burst ability instead of a sustained damage ability. I'm also thinking that the camp clear/sustain could come in here. Something like a small heal for hitting an enemy, similar to Kha'Zix's W. And yes, I do understand that Kha'Zix's Q is very low cooldown, but it also has a ton of damage to the point where it's his primary burst ability and it's reliant on a mechanic your opponents can easily play around. W Again, movement speed isn't very good on an assassin. I'm thinking maybe put the stealth on the W, and have it be something like Serqet from Smite's stealth ability, where she stealths and roots herself, but is visible within an area around her, and can reactivate it while stealthed to jump. R Again, her ultimate doesn't fit on an assassin and needs a rework pretty badly. I don't have any suggestions for something I would like to see replacing this, though.
I would try to come up with a full rework for Evelynn myself, but she and the entire faction of the Black Rose need lore reworks before any type of update for Evelynn can be made. She doesn't have a lore from which you can glean an expected kit. Her, and the Black Rose as a whole, have the lore of "Not much is known. All we know is that she's a member and Leblanc is the leader and it's stationed in Noxus." I would like to see something like the Mount Targon event, where all members of the Black Rose get a fully new lore all accessible from one page and the Black Rose as a whole gets a new general lore, maybe the release of a new Black Rose champion into the release of the Evelynn relaunch, similar to how Aurelion Sol was released and then the Taric relaunch not long after. I could maybe try to do the lore and stuff myself just for a bit of a challenge to tackle, but that all might be just a bit too much for a humble champion concept-creating fan. I think I'll leave all that up to Riot, and I have high hopes for the Evelynn rework. Thanks for reading, and feel free to tell me what you want to see from the Evelynn rework.

and maybe
. Note I did not include Shaco because I think he need that Master Yi treatment where the merge the ap and ad playstyle.
and
but their is limited or very toxic when they can deal that instant kill(knifekitty).
they are Ride and Die champions.
