He's underpowered right now, and even Morello said so. He's actually on his list for a bit of buff/rework... one of which involves hitting his sustain but putting it to something else to give him more threat.

Lanewick is alright, but his lane sustain is pretty overrated. He can be bullied very hard by very many popular picks for top lane. Not to mention, the cost of his Q is actually quite high. Other champs like Cho can sustain much better, while actually being able to do short engages.

Junglewick is just very weak... even remade Taric is better. His clear speeds are very slow, and he cannot gank before 6. You can make use of the sustain to try to outduel the enemy jungler because you have more health. The problem is that the enemy jungler can either outright kill you 1v1 (Olaf, Xin) or just right click away (lots of junglers). WW can't keep you fighting.

He also doesn't have much utility nor presence in teamfights. It's not often you actually get to stick to the carry for a while without getting peeled easily.

Honestly there really isn't any reason to pick him over any other jungler. Maokai has deadlier (and just as easy) ganks by Lv2, has free mini-wards and great utility. WW just got left behind as more and more champs get released.
