I tend to like to do stuff at night, when there's practically no one else on. Partially this is because of my rather aggressive insomnia, a problem I've had for years now. But there's also something peaceful about it - stripped of the vast majority of players, suddenly I can wander about in the world, queue for dungeons or LFR, do the daily quest without worrying about other people doing the same, farm for rares if I'm of a mind to. The world feels broader, more expansive.
Perhaps this is simply a legacy of my being a rather curmudgeonly sort, but as I type this it's the waning hours of the morning. So I now ask you, what would you do in the quiet moments of the night?
