Well its good to know you are so emotionally uninterested that winning or losing at Worlds means nothing to you and should mean nothing to anyone else. But if that is true why are you still posting in this thread so vehemently? Your kind of attitude is the exact reason I stopped play 40k competitively.If you're opponent jumps and starts cheering and dancing then who cares. You're the one who gets to make the choice if it bothers you or not. Friday I played the world champ and we both needed a big win. When he took out my Han he jumped up and yelled yes! Honestly it didn't bother me at all I was able to laugh at it.
Why do you choose to let others behaviors bother you so much?
