Annie bug

Hello guys, if you play Yasuo, like me, and play vs Annie, you have almost always a hard time. Its because, you cant block her stun. Everybody knows her passive, after 4 speels a stun, and with Yasuo, you have your windwall, but theres the problem, most times Annie uses her stun on her Q or R, and her Q is the only speel windwall can block, but heres the problem, you dont block her stun. Well, you DO on that speel, but she still has the stun, so she just uses W or R to stun. I dont know if its on purpose, but its SOOOOO unfair, remember when they patched the Twisted Fate windwall W? Thats pretty much the same, and you block the stun and end of story, but with Annie, you need to get a qqs or just keep your distance, i think they should patch it. What do you think guys?
