What's with the Evelynn changes on the PBE?
Evelynn
Shadow Walk (passive) re-stealth time reduced to 6/5/4/3 at levels 1/6/11/16 from 6 seconds at all levels.
Dark Frenzy (W) [ Passive changed to -"Passive: Evelynn's spell hits on enemy champions reduce Dark Frenzy's cooldown by 1 second" from granting movement speed for 3 seconds on spell hit]
Restealthing faster is nice but that's hardly the stage of the game where it will matter.
The big thing I can't understand is why you would remove Evelynn's ability to stick to targets completely, in favor of giving her a slight boost to the cooldowns that are already refreshing if she kills her targets. That's not a buff. That's a nothing.
Why are you even looking at her W?
If you really want to make an impactful decision when it comes to Evelynn why not ask yourself what an assassin really wants. Virtually any character in this game (except Evelynn) can sneak up on targets by simply using brush and wards intelligently. [Evelynn's passive only gives her player a false sense of security because she gets spotted way too easily]
Evelynn doesn't need an engage. Evelynn needs a disengage that can help her get over walls. You know, like every single viable character.
It also wouldn't hurt if her ultimate was capable of killing targets.
