Heh. I don't play anymore; I used to be a big raider until I decided to focus more on school. That's where the big addiction, overbearing responsibility and time consumption take place, in competitive raiding. I transferred servers a lot to find the right raiding guilds; my last guild, Purpose, was on Argent Dawn. Other notable servers I was on were Bloodhoof (way back when) and Area 52 for a long time. My character name was Aerniskliwbi, a Tauren Prot Warrior, and I was the main warrior tank or sometimes an off tank. With Purpose, we were the 6th guild in the world (although technically the 4th, but WoWstats bumped us back for some reason) to get the Conqueror of Ulduar Achievement. I, myself, never got the achievement because I sat out for a couple of the bosses and didn't get them for the achievement. However, I was present for all of the harder boss kills with no deaths.
Anyway, I'm past that now, and I doubt I'll be going back to it anytime soon. Don't get into raiding; it's bad for you.
