League of Legends (LoL) Question: Ekko jungle?

He's definitely good enough to be a solid jungler. When I've played him I've had the most success with full AP builds (kinda like an Evelynn style build).

Enchantment: Runic Echoes, Lich Bane, and Zhonya's Hourglass are all good. You could go tankier with stuff like Iceborn Gauntlet, Dead Man's Plate and Guardian Angel if necessary. Obviously Void Staff and Rabadon's Deathcap are good choices for damage.

I haven't seen a ton of Ekko jungle but the few good ones I've played against usually go full damage. Pretty fun champion, hope you enjoy! :)

I think it can be good in some team compositions cause it's got slow, stun, and can make some suprise gank. For example you notice a ward in the nearest bush to bot lane.You go home to shopping, amd when they think they are safe and they can easily start a trade, you ult back and make a succesful gank.
In the end, i think you must take it some compositions, like no mage in team, but it isnt the best jungler champion.

Ekko jungle is completely viable as long as the player is decent enough to make proper usage of Ekko's W. His gank potential is high as if he makes a mistake or the laner ends up 1v2ing, Ekko has a very reliable fallback, his ultimate. This means for junglers that are unsure if they are able to 2v1 a laner with high damage (such as darius or illaoi) ekko is a very strong pick.

Ekko's tanky build potential has been nerfed and no longer viable, as full damage is much better if the player is decent. Full damage is a much better and more viable option as his ultimate can make up for his squishiness. I hope this answers your question

TLDR: Yes if you can land your w and use ultimate properly

He doesn't have the best clear, but his ganks are top notch if you can play ekko well.

To be honest he is not really a strong jungler at the moment, but he sure as hell is fun to play in jungle in normal games.
