Lee Sin Nerf in 4.13

The shield only being up for 2 seconds I can live with, but taking a way the attack speed slow on lee sin's e? Most pro players have ALWAYS said LEE SIN IS PERFECTLY BALANCED, LEAVE HIM ALONE! I've heard this many many many many times. I myself agree completely that Lee Sin was balanced, yet now he is unbalanced again! Sometimes I sware riot doesn't even play their own game, they just randomly make tweeks to champions by rolling a die. I have over 150 ranked games as lee sin, in S2 he was my most played champion. He is currently my most played champion in S4. I've been playing him since S1. I've played well over 250 games as lee sin. Im tired of seeing him get nerfed, and nerfed, and nerfed some more! My user feedback? Well it's hard to make a statement here without being toxic. I am so utterly disappointed in you riot. IF IT AINT BROKEN, DONT FIX IT.
Thoughts anyone?
