I started playing because eeriely, it was everything I was looking for in a game. I woke up one day a few years ago and thought; "Right, this is my perfect kind of game - let's see if anything like it actually exists." I wanted a fantasy game with an open world, different unique classes, lots of story, and racial choices. WoW was almost unbelievably close to my idea of my perfect game!
I've flicked from faction to faction. I began on the Alliance, and have lots of nostalgia there. I also prefer how it's the classic concept of medieval knights and castles. Yet I also branched out to the Horde, because I love the High Elf/Blood Elf story and I like how most of the races are very tribal and in tune with nature (At least, before Garrosh came along).
I wanted to have a Druid as my main character, because I love nature magic in games and the idea of shapeshifting was just so cool. I also like healing.
I began as a Night Elf, as I love elves in video games. The Night Elf history which I found later was also brilliant. Yet when Worgen were released, I changed in a heartbeat. I'm english IRL, and being able to play as a victorian werewolf commanding the powers of nature was just too cool for me! :P
