Yasuo Ult

We... SERIOUSLY... need to change this ult. It is TOTAL crap. You know why? Becasue, and im sure many of you have noticed this, it will NEVER cast on teh first press. You know someone up, then you have to spam R to ult them. It may be intnetional, so people can attack the kocked up target before ulting, but it is the reason i lost last game. I had a 3 man knockup on 3 very low carries, so i warded when i heard the sound. I then pressed R. TOO LATE! It didn't cast first time, so I got caught out and died to three carries. They didn't die, came back to lane with extra gold, one of them used it to get a kill by about one bar, and proceeded to be jinx and carry the game with "skill" (a 1/12 voli who thought the meaning of kiting was "walk after the adc slowly"). The whole loss of the game was due to that kill, which allowed the jinx to get a few more kills and get super fed. The reason she got that kill was because she had killed me. The reason she killed me was because MY ULT DIDN'T GO OFF ON THE FIRST CAST and I lost my chance at a great play. This NEEDS to be fixed or I can't trust yasuo anymore. If he's this inconsistent and buggy (same game, a Leblanc's combo went through my windwall) then I can't play him. I can't be sure my abilities will WORK. Riot NEEDS to deal with this.
