Yes, Don’t let Riot pull the wool over your eyes when it comes to Evelynn. They have no plans on updating her (unless it's to completely change her), nor will they touch her lack of damage because they want to keep her that way.
Think of Eve as the Pandora's box of League. If Riot can keep her boxed up tightly, and prevent her from getting any advantage. They won’t have to deal with the skilless players, and whinny little fan boys complaining about how over powered she is, or that they feel there’s no way to counter her.
Fact. Riot has made her almost unplayable, and nigh close to un-enjoyable back in season 4 when they UBER nerfed her Q. The casting speed nerf, and the damage reduction on it made it all but unusable. I must also mention it’s pathing is crap, and rarely goes in the direction you line yourself up for because it’s not a target-able ability. It was viable back when she could speed cast it, but it’s horrible now because once it’s cast it has too long of a cool down to re-position yourself.
Her E is also in a pretty bad state, but slightly better than her Q because it at least deals decent damage, and was mildly upgraded at the same time her E was FUBAR’d. Her R is all but worthless, and is only good for slowing down some of the enemy team that it might hit do to it’s horrible hit box, and almost non existent duration (not to mention a cool down that makes it extremely laughable as an ultimate ability).
On another note, both her E and her R drop her selected target when cast, so you have to re-select your target instead of it persisting from one attack to the next. This is beyond sad as it prevents you from casting your ability's without double confirming your target.
Her W was nerfed to the point were she has to make the decision to either cast it to run away, or cast it to go balls deep and die because of the mana it consumes upon casting. This was a nerf that fundamentally smashed Eve into the ground because it removed almost all of her utility.
On principle alone a player is better off playing another champion for damage. Most of the games tanks deal more damage in one hit that Evelynn can dish out using her Q, E, and R followed with a couple auto attacks. This is evident with champions like Sion, Alistar, Malphite, Garen, and pretty much any other tank in the game that can one shot most squishy champs once they’re built.
Riot at this time doesn’t even want to call her an assassin anymore. They’ve gone so far as to try and pass her off as a backdoor tank... a TANK? are you kidding me? not only is she not a tank, she can’t even build into it, nor take the damage to sustain it when built like one. She’s not a fighter either because she doesn’t have the damage, and she doesn’t have the lane presence to keep in lane long enough to withstand a fight.
Many people on the forums keep saying "I like were she’s at because her passive is over powered". These people would be the players without tactical skill. The players that just want to shoot laser beams at it, or hit it with a stick. Personally I don’t think her passive is broken as far as how it plays out in the jungle.
At this point riot just needs to remove the fact that her stealth passive puts her into stealth on the screen. I feel the way to fix her passive is to just remove the on screen stealth portion of it. make her able to bypass yellow wards, and that’s that. no more going into stealth. she’s just invisible to yellow wards. in fact change it’s name to move silently.
does it remove her going through the jungle freely? no, not at all. in fact it welcomes the fact that she’ll be the only champion able to do that, but it will remove the almost worthless stealth bubble she currently has, and hopefully appease the whinny fanboy gods.
Once this fix takes effect Riot can revert her Q back to at least half it’s old casting speed. Remove the mana cost on her W, and give her R a cool down that makes it worth having. hell, even remove the shield from it, but make it at least last 2.5 sec instead of the 1 sec it seems to currently go for.
This my friend might actually fix Evelynn, and bring her back in line with other champions in a way that will ease "the Walking Dead's" Negan level nerf batting she's received since she was first released.
