Elfen I used to play the game ONLY at night, and it was hella fun playing with all the kiwis an aussies that were on the server I was on, you should really check out the Draenor ( PVE ) realm it's packed with people from new zealand an austrailia, europe, there's a couple guilds devoted to players just from those areas, so you'd always have people on to play with and have a fun time with.
I gave up on my wow ventures, the game is nothing but rinse an repeat, nothing new every thing's the same with a different gift wrapping, I played it since a couple weeks after the games release in 2004.
Tomorrow Age of Conan opens up to the world as a whole, and I'm diving into a pve server, there's some imbalance with Free For All pvp on the pvp realms and spawn camping but it's being quickly addressed by Funcom which is really nice on their part.
World of Warcraft is a great game, however the reason I think you should stay away from it (and why I'm mad at Blizzard ) is because it is addicting. This video is an actual broadcast from BBC explaining my argument.
