Anyone notice how poor Lee Sin/Nidalee have become?

Currently with the META surrounding tanky top laners and junglers, this makes champions like Nidalee and Lee Sin extremely weak as they basically thrive off squishy targets with no peel. Now even though Lee got no nerfs he is nearly absolutely useless as a jungler in this META and let me explain why.

I am an Amumu jungler main, and I noticed that for the very few solo Q games that I see a Lee Sin picked or a Nidalee in the jungle, they always end up falling off once team fights roll around. Usually they heavily counter gank me and sometimes do as well as 8/1 early game, now though this sets me behind, Lee Sin is known for his relatively poor team participation if he can't get onto a squishy. So compared to Amumu who does a lot of damage and can lock down an entire team effortlessly, Lee Sin really can't do much to avoid that. Leading him to fall off severely especially if he rushes an early Ravenous Hydra and ends up just being focused. Counter ganking champions like Amumu or Sejuani really doesn't set them behind very much since they have excellent clear time and basically scale off building cheap tank items like frozen heart leading them to be a lot stronger than champs like Lee, Nid, Vi, and WW since they simply can't compare to the amount of peel, cc and tankiness which Amumu, Sej and Gragas provide. That is exactly why I like Amumu so much, he is beter than Sejuani in my opinion, no one bans him and he is a hyper carry tank that can easily get fed and turn around an entire game with his Ultimate. I especially love him since he can melt a backline if he has and if you're really fed then a calls for GG.

TL;DR You don't need to nerf a champ for them to become weak because the game it's self will change over time.
