I love locks, I just suck at playing anything that can't tank. Currently playing a blood elf pally, but rerolled a troll druid which I will use to explore all of the changes.
I got burnt out on the hard core raiding during Ulduar while I was tanking with my DK. I now raid on a more casual basis, I still haven't taken the LK down mostly because my current guild really isn't into raiding soon to be old content. I might have to try and hook up with a pug group and get my Kingslayer title.
