That’s just life though, that’s not something to really be wildly upset about. It’s nice to have an estimated time rather than a “will it be noon or midnight? no one knows!!”, I’d rather blizz admit “we messed up, it’d gonna be a few more hours” than just leave us sitting at our desks twiddling our thumbs going “any second now…could be literally any second…” FOR HOURS!
At least a time announcement gives us a ballpark idea. If you take the day off and it takes the entire day to launch, at least you didn’t have to work that day? Don’t take days off you can’t afford to take.
