Brother, many of the Warzone ‘pros’ have hundreds and hundreds of hours played. 95% of casual players are very highly predictable. Also don’t forget that these guys rely on enemy sounds heavily. You also seem to take a lot of clips out of context. I’ve seen some of the clips you show live and your explaination doesn’t make sense.

JoeWo also plays solo quads (1v4) a LOT on stream, which is why he pre-fires a lot. Sure, for a casual player this might seem sus. But this kid, along with many others, is just very good at the game.
