Lee Sin - OP in soloQ or not?

Beforehand I'd like to warn you, this is not quite like the other Lee Sin post on the front page, but it is a reaction to it.

Personally, I do not really play Lee Sin, I got mastery 6 on him as I enjoy him in normals occasionally, but my ranked KDA is 4.5 / 7.3 / 5.5 over 4 games of which I won none. I suck with Lee Sin and I certainly am not alone. Regardless, I do not enjoy the bashing that Lee Sin players have to endure ("upvote if you just don't like Lee Sin"..) so here goes.

The statistics that people find the most interesting is his playrate which is an outstanding 37% and then his winrate of 49.8%. Most assume that a high playratio equals inexperienced (and therefore bad) players which would make the winratio seem unproportionally high. But that is simply not the case, Lee Sin players are in average very experienced, in fact Lee Sin has the 5th highest average games played. Considering that it seems kind of weird that he still has a negative winrate - why would the champion with one of the most experienced playerbases have so little success?

Let's keep this question in mind and take a look at how exactly Lee Sin players perform. Those with 1-5 games (the smallest player group) on Lee Sin have a 39% winrate - which is kind of expected. Outside of the boards people consider Lee Sin to be a very demanding champion that isn't made for casual use.

Those with 5-15 games (the second smallest group) have a 46% winrate which is a huge improvement. It appears that once the basic mechanics like wardjumps are not that hard anymore Lee Sin starts not to suck that hard.

Once players are in the biggest group with 15-50 games played they tend to break even with a 51% winrate. Given how high the skill cap is considered to be, one would expect the next groups to perform even better, but..

Both, the 50-125 and the 125+ group have only a 52% winrate. This is in general very mediocre or even below mediocre and also very low considering how high skill cap champions should have a good winrate with that level of experience.

To conclude, it seems that Lee Sin is doing rather mediocre except for his high playrate. You might argue that it is because many of those who play off role just pick Lee Sin as he seems fun, but that really doesn't quite explain the low winrate on the mains. Another possible point would be that his high pickratio means that people pick him even in bad situations so that this decreases his winrate, but seeing how much of an allrounder Lee is this can't be a big gamechanger.

BUT. There is one thing that hasn't been considered yet. And that is, obviously, competetive. Since we are in LCS off season now and IEM isn't all that useful to get competetive data it may very well be possible that Lee Sin is OP on this patch - in competetive. Let's remind ourselves that Lee was a strong pick at worlds despite being way less prominent in soloQ back then. Seeing how the jungle changes all benefit Lee (lvl 3 Krugs; higher jungle experience = better snowball for fast clear junglers) it is very likely that he is a god tier pick in competetive. We can't know for sure, but I think the Krug changes (and hopefully general jungle nerfs) might help with Lee Sin being potentially too strong in competetive. Other than that it's hard to say anything more than that Lee Sin is not OP in soloQ.

tl;dr: Lee Sin is still not easy to play (39% winrate on newbies) and the overall Lee playerbase is very experienced but performs rather poorly; he is not OP. However, it is likely that he is too strong in competetive due to the jungle XP changes, but we can only guess. Let's hope Rito nerfs the jungle.
