User blog comment:Kait-zero/The Stealth rework, why Evelynn needs it but Twitch doesn't/@comment-71.67.243.178-20120327104132/@comment-3970297-20120327153003

Eve was nerfed sometime before the month of October of 2011 since. They said the rework would be ready within the end of October...

Given the fact that they are well over 6 months since that time, I think it's safe to say that Riot has NO idea whatsoever on how to solve stealth, nor have any means or reasons to delay it for this long without saying anything.

Personally, I would buff Eve up to more viable, playable status that keep her at this stage, since obviously they have no trouble coming up with more mechanics for new champions.
