ZED "Q "BUG !

Dear Riot ! Sometimes (many times) Zed W + Q's wont activate.... The Single normal Q's are good, but the Shadows ( W ) Q's are wont activate ( won't come out) I mean when I fast press W + Q , there will be only 1 Q , and the shadows Q wont come out !!!!!!!!!!!!! -.-" its really annoying . I deal 0 DMG , i cant play like this. Zed is my main and i only play Zed. This makes me sad , and i dont want to play anymore. This happens in every single GAME.................................. PLS FIX IT !!! Btw if i press the W and then after a few seconds later the Q it still wont come out form the shadow.... PLS FIX THIS FAST !
