Hey
There is a large group of Hammers who play well to 3-4am CST if your are ever on after your night shift. My global is /@Undeadcyborg, welcome shoot me a message.
Heck, there are a lot of us nightshifters who play all through out the night into the wee morning hours. Some being on BMT others running rampant elsewhere but all in all I've seen a bunch here and there.
**edit note**
I'm on generally during those times and yeah, you'll find Elly (post below this one) and I running around so you can team up with us if you see us running around.
Heyas, welcome to night watch 
I live in Australia, so im always on when others are in bed. Send me a tell if ya ever feel lonely and want to team on @elysan
Laters!
I work from 4:30 to midnight CST and usually play during the day, if there is anyone that is in a similar situation I am currently leveling up a new Archer/Dev blaster if you want to team up. He is level 9 dark elf wannabe named Azireth.
