easy jungler ?

Master Yi definitely, literally spamming one button all day long

Amumu is the easiest character you don't need to do anything you just need to press q and r and that's it easy win

i suggest rammus, he is very easy to play and kinda meta right now

Master Yi is obvi a good place to start, not very complex.

at this point you can jungle almost every champ, but i would keep it to bruisers like vi

Teemo or Nocturne are quite easy jungle champions, either that or kate

Master yi is good. But i recommend to training Viego. That's easy too, if practice 1-3hour

Master yi was always easy..
But try also noct, amumu, and if u want somethin more harder try KAYN for sure

i think warwick so much bettter

Rammus best choise if you wanna grab beer and ride on all map
