One of the earliest and most important lessons you can learn about life is that when you get lucky often enough, it stops being luck. In esports this is especially true; your opponent's 12th "lucky" headshot is probably not luck.
But getting a bit more meta, this also applies to tournaments and organisations. ESL is a great company, doing wonderful things, but their tournaments do seem to suffer horrendously from network problems. At IEM Global Finals this year the WoW tournament was set back by six or so hours, for example, and back at the American qualifier last season things were even worse. Today is the 2nd event of the new season and they're having more problems (glad i got up early to watch -_-;).
I've generally been willing to give them the benefit of the doubt. WoW is not a good tournament game in many ways, and one of those is the lack of LAN capability. But there is no WoW today, and although Quake Live's offline mode is fairly new there didn't seem to be any problems at QuakeCon last week. So when does bad luck stop being luck and turn into incompetence? I'm not sure, and without being much of a tech-head myself i'd hate to point the finger, but my good will is starting to run out.
