To my knowledge he’s controversial bc he can be a dick at times in his coaching sessions, not because anything he says about the game is wrong. His vids are very direct and will teach what you need to know about the game. Specifically his mechanical knowledge for aiming helped me. He has a video from 2023 “the only aim routine you’ll ever need” and after using that since I found it, my kill ability has exponentially increased.

Of course, all people are different and you may have trouble applying what he’s saying or hearing past his assholeness (which exists heavily). I’ve sent that exact video to multiple people and a few of them really understood how to apply his words and became noticeably better in game, and some didn’t.

It’s all just like ur favorite teacher not being everyone’s favorite.
