checked out the thread, seems pretty sketchy to me... the clips from his stream look mostly legit except for the start of the KR Zarya clip and most of the Anubis Zarya clip. i honestly couldn't tell you what is up with the weird shaking around the soldier in the Hollywood clip, that shit was just strange. maybe a bug with the aimlock toggle that sent it back to S:76 repeatedly?
i won't be one to judge the EG vs Kungarna stream clips because earlier in the game's history there was a spectator bug that made flicks look like aimlock - Taimou even got accused of aimbot because of it. in all the footage i've seen of Corey, when the toggle is off (if it exists), his tracking seems pretty decent but definitely not Tier 1/Carpe-level, but the flicks i mentioned above look too good to be true imo.
that being said, every time they showed Corey on today's stream it looked clean. there was just no way he could contest Carpe's skill
