Because of this schedule, I don't usually see what Azeroth looks like in the middle of the day. With darker nights about to make a return, it's likely I won't see too much of the sun while I'm playing unless I'm in specific areas. Oddly enough, that doesn't bother me a bit. If nothing else it's a quiet and constant reminder that yes, the hour is late and yes, I should be thinking about things like sleep before too much time has passed. Sure, the clock is another reminder -- but it's the dark skies that give me an immediate visual cue as to the hour of the day.
I'm just one outlying example, though -- and when I'm online, there usually aren't that many people on. So I'm wondering, when exactly do you guys usually play? Middle of the day? After work, but before dinner? In the wee hours of the morning? Is the possibility of darker nights in game something that excites you, or something you'd rather not see? When do you prefer to log on and spend some time playing the game?
