eeedon't captain your first season of ESEA or 6s. You'll get upset and not know how to handle it and probably kill your team
don't captain if you're not good at communicating or working with people long term
don't captain if you still have problems as a player when it comes to tilting
leading a team brings out the absolute worst parts of yr online personality and you'll very quickly get a reputation as "that guy" if you're barely keeping yourself together while trying to coordinate 5 other people barely keeping it together
I made pretty much all of these mistakes my first and even my second season, and I very well came close to killing the team multiple times. I think that experience though made me grow as a person much faster than just being on a team would have, and I can only thank my teammates for putting up with my incompetency
