New Eve is extremely team dependent, especially if you are running DH or Electrocute. Her rework, imo, always made her more niche.
You could tell this in season 7 end, when for the last month or so, she wasn't even viable enough to live at Baron, and barely lived at drakes (Old runes had no way for her to sustain, and her itemization had no in combat sustain)
She's just not self-mobile enough to be a popular jungler. By Self mobile..... I mean..... her only mobility is built into attacking things with E.
They also gated her spammability, and gave windows where she literally can't do anything in a fight. 3-4 seconds of doing nothing is a big deterrent as a pick.
Another problem: People have shifted from independent thought on building a champ, to hive mentality.
Phase Rush actually makes her far more interactive than either Electrocute or DH, gives her far better survivability, stalking pursuit, yet people zerg Electrocute/DH all the same, because it's early game, secures more kills, etc. BUT IT DOESN'T ENCOURAGE TEAM PLAY.
Keep in mind the reason people chose ugly Evelynn was because she was two very different champs: Spell caster assassin, and a Brawler. I almost exclusivly played her AD pre rework.
was far nastier than going AP. You could ignore her entire stealth premise, and brawl the game away as a direct up front engager. R First = No escape.
Rework gave opponent plenty of escape.
