Azir`s Ultimate does not work most of the time

Yup, confirmed. Just played a match where I had 2 ults in a 36 minute match that actually pushed enemies. People on both teams were commenting on it. Every single other ult either failed to push a single target, or didn't push all of the targets. He needs to be disabled until this is fixed. Pretty major issue. Copy and pasting this in every thread regarding this issue until Riot responds.
