Did Shyv fall off s7?

She isn't that strong right now sadly, still very playable though

i dont think she has truly been viable since stated devour meta

Junglers that are good right now are ones with good early game or with utility.

Prime examples; Lee Sin, Graves, Kha'Zix, Hecarim, and Ivern.

Shyv isn't that strong early and can get kited to oblivion mid and late. Consider the top ADCs atm are like Lucian, Cait, Ez, and Ashe. All of these champions are pretty good at kiting (even more so in Ez's case since IBG is returning as the more common build atm). Shyv also doesn't provide much utility, either, besides her ult, which requires her to dive into the enemy team to utilize it.
