Yeah, at this point she feels kind of like a worse version of shaco. She wasn't exactly doing so great before the jungle changes hit, and nothing within them even remotely helped her, as she has no real sustain and no defensive steriods. You "can" play her and it "can" work, but most often it ends with destructive results, especially at higher elos when people realize that if they walk into your jungle, they can find a half dead eve and kill her with one spell.
I still think it's funny that when warwick has a 60% win ratio it's "gamebreaking", but when eve has a 38% win ratio it's something that can be ignored. Kind of a slap in the face to have them release a patch where they supposedly fixed all the UP junglers, but completely ignored her.
TBH, I would be fine if her stealth could be penetrated by wards, as long as it would allow her to be viable. Or I'd be fine if they transitioned her back into a mid lane champion, which is a bit less toxic because you can see when she's gone and ping accordingly. I just love her playstyle and want her to actually work. It's like she's been infected with chronic Underpowereditus, or something.
-Sidenote: elise needs some help as well. 42% win ratio op.
