I've been thinking of this since Sick and Ardiis (but there are another exemples like Zombs, Shaz, etc...).
Why esports pros don't act like pros? Look what Sayf said about his teammate callings. Is he really thinking that's good for the team (and mostly Redgar's confidence) to speak like that for everyone?
I've been seeing this in CSGO aswell and they're all the same. I don't watch LOL or other esports, but I doubt that is different from what I see from those guys in FPS.
