That's kinda with everything - when I first started playing tennis when I was 10 I was happy when I hit the ball over the net. Now I'm happy because I'm beginning to ace people with my serves. Soon I'll only be happy when I always win tennis matches, and that competitive streak is in everything, not just mcsg. But it's strange that you don't feel happy when you win, like wat even tennis pros like Nadal and Federer break down crying or are smiling from corner to corner of their face when they win Wimbledon or when playing a good game. Maybe your not getting enough of a challenge? Try going on us1 - 10 servers the pros hang out there x3
And complaining about teams really? Teaming always has and will always be a part of any hunger games server / most pvp servers.
If you can't beat them, join them

Or do what I do and set fire everywhere >:'D
