There is no such thing as a perfect time, but there are better times than others. 6pm EDT is bad for pretty much everyone, though US and EU get the worst of it certainly.
It's relatively standard software industry practice to do maintenances in out of the way times to lessen their impact on users. Don't get me wrong - I'm not saying Relic owes us anything or that they have to do it or that they suck or anything, just pointing it out in case.
As I said, pretty minor. It's just an easy thing to do to avoid extra griping.
EDIT: Sorry if it wasn't clear - it's not "US and EU are inherently superior, f the rest of the world." It's more "when choosing a time you're going to impact somebody, so try to impact as few as possible."
You might feel different if you lived in a country that got screwed over Every. Single. Time.
Weehamish, if you hate the game so much why do you stick around just to make a bunch of negative comments? Move on with your life and go play something you enjoy. Trust me, we'll cope without you.
I've got a better idea - we should give them a six man squad, and give half of them Mosin rifles and the other half KR98 rifles. Then do the same to the Russians. Then do the same to all the other units, and we can all be happy because all the sides are exactly the same. That will be fun, right?
