If Lee Sin is god tier in this jungle, its time to admit Lee Sin is a problem
And not blame it on metas forcing other junglers out, poor itemization making other junglers weak and so on.
The truth is, we won't be able to determine this until competitive play starts back up. From a solo queue stand point, Lee Sin has always remained below a 50% winrate. However, keep in mind he has a ridiculously high pick rate and ban rate, which should be alarming in its own right but thats not enough to condemn a champion to death. Although its been done in the past to several other junglers.
The point is this: this is the 3rd major jungle change we've seen. This change goes above and beyond anything we've seen. This jungle is more about strategic approach, considering routes matters now. Objective control is still important but its enhanced in gameplay times a million now.
Yes I know, Warwick is an abomination right now but Riot correctly forecasted that he would likely be a problem. After his changes and with competitive play starting up soon, we are going to see whats really strong. In my mind, all indications suggest Lee Sin is still a god tier jungler but I will want to see more than just my suspicions to prove that. And if he is, Riot, after all the major changes we've seen to the jungle the past 4 seasons, its time to admit Lee Sin is a serious problem in this game. Because history tells us when Lee Sin is good, he dicates whats good in the jungle (I.E something that can keep up with him until its brutally nerfed). And if Lee does that again, theres nothing in the world you can do to change that except address Lee Sin for real this time.
