The hardest thing about playing WoW during the night shift is watching your standards for success drop as people who aren't as demented or as sleep-deprived as I am realize they have to do things like sleep and get up in the morning. Since I know I won't be able to sleep I'm fairly cavalier about it, but as the night transforms into early morning people go from let's clear Heroic Arcatraz to let's try one more time to kill this annoying boss and call it a night. That's right, Zereketh, you know who you are. I'm somewhat of a perfectionist, so it can be very frustrating for me to tank a boss over and over again and see the DPS dying from stuff I can't do much about, like the Void Zones he keeps spawning right under the clothies' feet, especially when you get the boss to 1% six times in one night.
Not that I'm bitter or anything.
