i feel like evelynn has been a viable champion for maybe one tenth of her existence in this game

I think the majority of league players are fine with this.

She exerts a ton of pressure on the map just by being in the game

She's really oppressive when she's popular or strong

Perma-invisible assassins don't deserve to be viable

I would rather deal with tank fizz again, because at least I can SEE HIM COMING AND WARDING ACTUALLY MATTERS

that would be One tenth too much.

Perma stealth is too hard to balance.

I actually think Evelynn is currently pretty strong right now. Runic into Lich Bane or IBG, and then full tank (Deadmans, Banshee's/visage, Steraks, not frozen heart imo - since it offers no health). Insane movement speed, it's really hard to get away from you. High burst, you can 100-0 high priority targets pretty well. Tankyness - with a 5 man ult you're almost unkillable, and even without, with proper kiting and manoeuvring you're unlikely to die while still doing tons of damage. She's in one of those below the radar positions - not overtly strong, but highly effective in the right hands, which is where she should be imo, otherwise she ends up being an oppressive nuisance that calls for an immediate nerf.

Bad design, outdated - also not an interesting character from a lore point of view.

Step to buff Eve.

1. Buff Vision wards.
2. Buff red Trinkets.
3. Buff Oracle Elixir.

Now that anti-stealth mechanics are viable again, you are free to buff Evelynn.

Lets just put 50 second true stealth back on her W and also give her back her stun. I want to go back to hard season 1 strats.

Until Riot changes her passive so that her stealth is a mana-draining toggle (which I think could be a lot easier to balance) , she'll be dumpster-tier.

Is Evelynn playable? Yes Is Evelynn viable? Kinda? Is Evelynn Fun? No

After assassin update (which is supposed to come after mage update) Riot will most likely: a) rework Evelynn removing her long semi-stealth for some 3-5s true stealth (something like twitch) b) will remove stealth from Evelynn alltogether c) won't touch Evelynn d) may introduce medium-long duration of true stealth on Evelynn (which I hope will happen)

Eve has perma stealth, and she's an assassin.

Both long duration stealth and assassins are nearly impossible to balance, and for similar reasons. They are either exceedingly overbearing, or useless.

Eve is a bad champion design that exists due to the fact that this game is a spinoff of Dota, and early design champions reflect it.

She's kind of like old poppy in the fact that she has to exist undertuned to perform at a barely okay level, otherwise when strong she's ridiculous.

Just wait til urf comes out, then Evelynn will be god tier again lol.
