Really depends on the circumstances. I had a lower geared Warrior tank in WP the other day while I was on my WHM. they said they wanted as fast as run as possible so I was dropping so many holy's I knew I was gonna get beat to hell. Guy never lost agro, not once even with chain Holy's so..he got my commondation. I'll give it to dps a lot because it's not fair they have a harder time standing out.

Just because a tank held agro under normal circumstances isn't a reason enough. Someone has to stand out and show they play their class really well. Clutch moment they held together. While i'm on my Pld maybe we got some bad timing and pulled the big ton's and the healer managed to keep us all up. that kinda stuff.
