I've been playing World of Warcraft for quite a few years now, and over the years I've raided with a few different guilds, and recorded some of the boss kills. I only really started recording some during Wrath of the Lich King, and stopped raiding sometime during the Mists of Pandaria expansion (for which I didn't record any videos either). Who knows if I'll start up again, I'd kind of like to get back into it at some point.
During the Wrath of the Lich King expansion I was part of a guild called Dusk till Dawn, on the Aman'thul server. I played a restoration (healing) Druid during this expansion, where previously I had raided as a Warlock and Mage.
When the Cataclysm expansion came out I decided to make a fresh start on another server, Saurfang this time, and switched (back) to playing a Warlock. I joined a guild called Cryptic, and have stayed there ever since.
During Mists of Pandaria I raided for the first half or so of the expansion, but didn't record anything. The only video I recorded was my defeat of the Warlock 'green fire' class questline boss, who was pretty damn hard at the time. Felt pretty good to finally get him down :P
