Is nautilus jungle still a thing?

I mean, you could? But his clear is so slow from what I remember. Can't really think of any tanks in the jungle that are good right now. Maybe Gragas?

Also Rammus

while they are trying to improve nauts performance, as a main of the champ hes not that great anywhere right now. And there are much better choices that do the same job such as sejuani

Nautilus is considerably below average in regards to jungleing. His clear is bad. His farms incredibly slowly(Support will have more gold than you.). His ganks are terrible, a countergank is pretty much a guaranteed lossed fight considering how weak you are comparatively to every jungler in the game. his build is awkward.

Nautilus needs a lot of help.
