So working people coming home would see their game unplayable due to peak time maintenance.settle down. they cant do maintenance on the server(s) at everyones off-hours. go outside and run around or something. your not the center of blizzards universe.
Not sure in what part of Europe do you live, but in most countries in less or more serious companies there are people working night shifts to satisfy their customers. With short(!) maintenances being done during off-hours, so most people don't even know about those.
Edit; missquote, sorry kliffharry.
