Aggressive early game junglers?

Definitely Shaco, however, he really has to snowball or he is somewhat useless.

Xin zhao

Nunu isnt really aggressibe in anny point of the game ? Unlese you call stealing camps agression

shaco is a gos of the early gank nidalee reksai udyr all do good early gans

so does sejuani cause her q is enough her ult is nice but not needed

try zac, maokai, and mid

early game aggression and impact can take on many different forms and also, "early game" is from lvl 1 until 1 item, so about 10 minutes average. but by 10 minutes, you are allready about lvl 8-9, so thats the early game for you, and ALL junglers can be impactful during that time in one way or another.

if you mean invading and assassinating the enemy jungler before lvl 6, lee, shaco, eve and nidalee are for you. if stealing enemies camps is your thing, nunu and rexai can be added to the list.

if you want to dominate the enemy jungler after lvl 6, nocturne, master yi and shyvana would be your thing. thats what i play. i think cheesing people at lvl 2-3-4 is really boring and doesnt rely on skill but rather on chance.

Shaco, Sej, J4

Lots of choices.

Xin Zhao is the strongest 1v1 champion in the game early. Has insane clear time and sustain in the jungle, and great gank assist. My personnel favorite is Shyvana. Her lvl 1-3 clear is average, but after your first back she becomes ridiculous. Devourer + Botrk gives her an amazing amount of power farm potential and absolutely destroys other junglers in a 1v1. Especially with challenging smite if you go that way. I typically have the same CS as my solo laners at 20 min, without ever taxing a lane. All from power farming my jungle, counter jungling, and still maintaining lane pressure.

. Don't listen to all the haters. Shes fine to play with once you learn her. She just has really shitty match ups
