[GAMEPLAY] Yasuo's dash + Azir's Emperor's divide = Yasuo Rocket
I think this has something to do with Yasuo putting down his WIndwall then Azir putting up his Emperor's divide going through the windwall and right as the Emperor's divide comes through Yasuo dashes towards Azir. This caused Yasuo to be infinitely dashing into the wall and getting knocked upwards for the entire duration of azir's ultimate. (I noticed that there's one sand soldier doing the pushback animation so it's definitely related to Azir's Ultimate.)
idk, it's hard to explain with text so I've provided a video (might not even need the windwall, just yasuo dashing up against azir's ultimate on initial cast. MIght be hard to consistently repro.
Patch 6.9
EDIT: the slowmo is actually .25x speed not .5x
