I am looking for some junglers/get in the habit of using them again. Any suggestions of what junglers I could reincarnate for myself?

My favorite jungler by far is Nautilus. With a competent damage dealing team he will shut down the other team forever.

I enjoy Shaco, nocturne, Shyvana, Hecarim, Mundo, twitch.

Lee Sin, Skarner, Malphite, and Renekton () come to mind.

But Lee's my main man.

Udyr, Malphite and Nunu. Getting into Junglesticks.

Pantheon is amazing as jungler ganking wize from lvl 2 on and fun to play.

I don't jungle much, but when I do, it's with Alistar. He can be build incredibly tanky and I love playing him

Mundo if you can land skillshots and understand his regen
Twitch if you don't mind last hitting everything and risk pissing off your entire team
Blitzcrank if you know how to rune and gank properly
Shen if you have good map awareness

Now, if you want to be an *******.
Yi if you think he's so goood omg OP
Eve if you're a troll
Tryn if you want to piss your own team off and fail
Amumu if you just want to faceroll and pick up mostly assists.

I've been jungling Darius a lot. hes pretty good. They tend to focus you though so you need to build tanky.

If I have to jungler, Alistar and Xin are the pretty fun.

I wouldn't advise getting Xin at the moment, because when you're picking Xin, you're pretty much hoping for a quick less-than-30 minute win.

But Alistar jungle is a lot of fun.
