ive been really thinking between nocturne, maokai, shyvana and lee sin.
i havent been seeing many nocturne and maokai but i think they are really good junglers especiallly lvl6. and i also like shyv alot because of her potential to counter jungle and her fast clear times. the last one is lee sin, i dont reallly know much about him but he is considered tier 1 and alot of people play him so...

help me choose a jungler to buy
any comments or recommendations are helpful

Nocturne is the easiest most consistent one of the bunch.

Nocturne, although his kit is kind of boring.

Lee Sin requires a lot of skill to play effectively. I like Maokai because hes pretty easy to play and his ult is really good in teamfights/objectives.

skarner.

i already have skarner looking to expand my champions of junglers
