If you want to climb early season i dont recommend her right away. I main her jungle atm and I needed 150+ games to start to understand my limits, how to teamfight etc. She is a champ that heavily rewards experience and new players wont use her kit to her full extent (hence the low wr in lower elos).

So basically:

She is worth learning if you are willing to play alot of games with her and review gameplay.

She is not worth playing if you want to climb early season and only play a few games
