League of Legends (LoL) Question: Xayah Jungle

Her clear speed will be okay I guess. But the main problem is that her CC is delayed because you first need to get some feathers for her root. But I believe it's still possible though. Chilling smite and Predator or especially Glacial Augment with Blade of the Ruined King can give her enough time to prepare her root.

Twitch is more viable as his W can slow in an area and he stacks his E passive over the time of the gank. all he needs is red buff for a cheese kill whereas Xayah will have quite a hard time landing any CC even with redbuff

Xayah isn't much of a ganker, that's your main problem here. I think your engage sucks. You'll have to land Clean Cuts on a guy that's already moving sideways, so even if you facerush people with e.g Predator, it'll be very hard to land your root.

Basically the counter to Xayah is to dodge sideways, and here you want to engage on people who are already moving sideways, you're kind of countering yourself.

How were you planning to engage?
If you havent noticed; many (alomost all good junglers)have an way to engage.
Vi has her Q, Warrick can R and stick on champs with Q, Zac can E, Skarner uses runes and so does hecarim ect ect ect.

Which is not to say that the ones I mentioned are considered tier 1 jungle champs but I listed them so you can compare Xayah's kit with champs that have an kit that is more suited and probably designed for the jungle.

Xayah needs time to set up her damage (with the feathers) and doesnt have an quick engage/disengage.
So yea, do with that info what you want but it seems like an silly idea.

You can always try though, just because something is meta doesnt mean you can not try difrent things.
Maybe you stumble onto something that will become the new meta, who knows right?

Just by looking at her kit it seems like an fruitless idea though.
