I Know it's the Wrong Game.. But Look up the Song "The Tank is Down" and "You Pull it you Tank it" on You Tube...

IT'S ALWAYS the Tanks fault... even if the Tank is 100% perfect and manages too survive the while instance without a Wipe or the Healer Dying.
Somehow i Find it Hilarious that we get DPS that Charge off alone and Attack things in Groups and think everyone Else is a Bad Player because they Working together...

And yes it has Happened.
