easy jungler ?

Most Tanks like Amumu, Sejuani, Volibear are very easy to play

I don't play much in the jungle, but the easiest to play is Jax and Nocturne. Kayn is also cool for beginners

i used to jungle with jax back in the day,rengar is also very good

Master Yi, no brainpower required! I literally got from bronze to plat in 2 days with him

Hecarim is easy and fun. very enjoyable to play. it would be nice if xin was in its old power

I think Nocturne and Warwick are both very easy jungle champions, both have self heal with not too much mana usage.

I always love Amumu has good ganks, game changing ult if you land it correctly

Udyr or Dr Mundo are two incredibly easy junglers because they easily rush through the jungle.

Easiest jungle is Rammus, Master Yi and Xin Zhao.
And the best part is they are a lot strong.

Most easier jungle is Rammus, Second one is Xin zhao.
Rammus is a good tanker, and Xin zhao a good fighter, choose what you prefer.
