Now, I don't know a lot about the state of e-sports these days, but when I saw this it made me feel fairly embarrassed for these people, and the championship events where this takes place. If this behavior is the norm in these types of events, I can understand why the rest of the world see e-sports "athletes" as a bunch of angry obnoxious teenagers. It definitely makes me want to not follow events like this. But then again, I might just be getting old.
I'm sure not all professional gamers are like this, even in COD, which makes me think that this is just how championship events are played, psyching out your opponents and what not.
Should it be acceptable to behave in this manner at e-sporting events? Should it be banned? Frowned upon? Or maybe encouraged? Is it just a part of the sport?
