Buff Lee Sin, nerf Azir? (Meddler answer plz)

Many said Azir is the Ap Lee Sin, difficult to learn but with great reward. They got so many similarities, the dash, shield, engage and disengage, both of them are bad in average players and god-like in top teir players.

so why Azir got nerfed while Lee Sin got buffed?

Azir got a nerf which ruined he's whole skill set. Shurima shuffle is much difficult now, ppl can just walk away from your dash and your ulti miss. I am not saying all Shurima shuffle is unachievable after the nerf, but its obvious that its much more difficult. Especially, when you trying to push ppl backward, more than 30% of your ulti will miss because of the nerf. If you want a secure push back you now have to give your flash out. And riot now telling me they will buff Lee Sin.

Here is the reason riot buff Lee Sin:

"These are buffs intended to give power particularly to players who aren't amazing at Lee Sin. We like that Lee Sin's got a pretty steep mastery curve that really rewards practice, but it's a bit too extreme, making it really hard to put him in a good spot balance wise (if he's balanced in top tier play he's very weak for the average player, if he's at least tolerable for the average player he's probably too dominant in top tier play). They will add a bit of power to competitive Lee Sin play too, we're looking to avoid too much of a buff there though.

^^^ Try replace the word ''Lee Sin'' with ''Azir'' The way they treat Lee Sin is totally opposite with the same case on Azir.

Average player bad at Azir, top tier player too good at him. Riot : Nerf him because top tier player too good at him.

Average player bad at Lee sin, top tier player too good at him. Riot : Buff him even top tier player too good at him.

Why Azir got nerfed while Lee Sin got buffed? Or is there any plan to buff Azir with a weaker CC: 0.25/0.5 stun or 99% slow a sec like what talon got?
