I don't understand the "ZOMG LEE SIN FREELO CANCER" hate?
I'm maybe in Bronze and I may not know much, but I just wanted to give some of you reading my 2 cents.
Lee Sin is imo a tricky mechanical jungler who depends on the early game as he falls of late game. Lee has a high skill cap and most people don't utilize him and his kit well until high elos.
According to OP.GG, Lee has a 45% winrate across all rank for the past month. Jarvan on the other hand, has 53%.
So while Lee does have very high mobility and play potential, most of it is never utilized as his skillcap is very high and I feel like most people who play him doesn't know how to use his kit, atleast at low elos.
Feel free to downvote all you want, but I just feel like Lee is fine the way he is. I don't find him much of a threat. Now that may come off as biased to some of you who have a passionate hate for Lee, but hey. That's just my opinion.
I find Lee mechanically fun to play with all the plays capability he has, but other junglers like Pantheon and Vi far more better.
Most of his plays come from LCS anyways. -cough- InSec -cough-
