Well pugs can be awesome and really bad.

I tanked a couple of pugs last night, and I made a bad pull. It was clearly by fault, as I misjudged the distance to a pack of mobs. On top of pulling 2x 3 elites, one of the dps got feared into a third group and then hell broke loose.

I laughed while trying to tank the 8-9 mobs at once. Hit all my CD inkl. barskin and hit challening roar. Somehow we managed to take down all these mobs, only because the other guys did a great job - laying traps, containing the mobs etc. etc. and the healer - another druid - did all the right things.

You might be able to tank 12+ elite lvl 80 mobs when you are properly geared, but i'm not, and after the bad pull I apologized and we went on - now that was fun
Some of the guys probably shook their head at me.
