No, not as a tank. I'm quite awesome, tyvm. But of late, I've been raiding 10 man content on my DK as frost DPS and frankly, I'm not happy with my output.

Last night was a good raid despite having two subs, both excellent player but both on their woefully undergeared alts. I had to bait them into coming and their mains need nothing from Ulduar 10, so.....and the warlock (alt of fury warrior) wearing blues, a few crafted lvl 80 epics and some lvl 70 epics wasn't too far behind me....
