trashnow that it's almost guaranteed that the top players aren't hacking, I think it's notable to point out that their clips still look weird as fuck regardless, and if they weren't hacking that means the server replays are terrible at capturing move movement, making weird mouse movement (as many FPS pros tend to have) even weirder
that's... worrying. being able to see someone's real-time replay is supposed to be a useful way to check for cheats, yet replays are making innocent people seem fishy
I have a feeling Blizzard will iron out the replay system by the time competitive matchmaking lands in a month. The 60 tickrate will probably also help a great deal.
They're usually very good with replays when it comes to competitive titles, although the only real competitive games they've had in the past that needed replay systems were their RTS titles.
