LOL@ people complaining because they won't get the patch that's most likely to cause technical issues of any patch ever, until a week after NA gets to act as the canary in the coal mine.
99.9% of the Euro server population benefits from this decision, and only the .1% that might realistically get a world first suffers. Same for asia.
If you're in Ensidia, Stars, Paragon, etc then I could see being a bit upset but if you're not then seriously what are you complaining about? Just because some Euro guild gets the world first it doesn't mean that YOU accomplished some thing.
