Playing sports through college has taught me one thing and it's that if it isn't dirty everything is fair game. The mental side of things is equally as important as the physical aspect of any sport. This includes e-sports. Talking shit in a match isn't allowed but if teabagging an opponent gives your team the mental edge then it's the responsibility of the players on the receiving end to ensure it doesn't effect them. I can't speak on CLG's behalf as to whether or not it affected them negatively nor would I imagine something like that would be admitted to as it would open the floodgates for other teams to expose a weakness. This is such a non issue that it's laughable. Anyone who's sensitive about this topic wouldn't survive a physical sport. Being professional doesn't mean being a princess.
