Aaaam I think Aatrox is kinda bugged atm on the live servers
Basically Aatrox's q procs Titanic Hyrda, i think the problem here is that the q counts as a basic attack (jax's e blocks it completely) Now if that is intended, sure it makes for a nice buff tbh, it feels good What is not ok is the fact that his w also procs titanic, not sure if that is intended.
Edit: https://clips.twitch.tv/VenomousAnnoyingRaisinTBTacoRight i included a short clip to demonstrate this.
