So myself (geared DK tank) and a resto shaman friend(also geared) started a H CoS run... and since the only way to get people into doing that late at night is to spam it as a timed run. throughout the run we had 2 lackluster DPS... a 1k DPS rogue and a 1650 DPS DK. By some miracle we succeeded in timer. However i had booted the rogue after the gauntlet on the way to malganis.
reasoning-
Doin 1kDPS? WTF?
During the gauntlet i was spam AoE aggroing everything since i knew between tank CDs adn gear with the healer i had i wouldnt die. the rogue insisted on spamming Crip poison on EVERYTHING even after i asked him to stop.
based on above 2 factors i couldnt see myself carrying someone to a drake mount so he could show it off like he was good.
Last thing-my shaman friend and myself both already have the mount so it wasnt anything to do with that
