Nithilak (pally, 32k) pugged him tonight in HoL. He kept aggro okay and doesn't look like he's got a raid.
Nerpic (DK) I know him from bumping into him several vaults in a row before ToC came out. I was impressed because he didn't murder any healers through failure to pick up adds on Emalon. In that timeframe, I rarely let anyone else OT because the adds hurt non-tanks. We struck up a chat a couple times and ran some various groups, but I haven't spoken with him much in a while. His current spec is blood/blood and his gear looks like he's been to a ToC or two but isn't a regular (or only just started). He could probably be convinced to go tank again.
Healers, shammies... I haven't had any luck on that recently.
