With my tank in some 4.2 gear, thought I'd go in to Heroic Grim Batol for another shot at my still uncompleted "cataclysm dungeron hero" achievement.

with some 4.2 gear, my tank can survive with a lot less healing so i went in with 4 elemental shamans (tank is pal).

After an afternoon of figuring out a viable strat, think I have one way of downing this boss in heroics. My shamans are mostly in 4.1 gear.

Here's the youtube link of the fight in realtime and HD for sharing..the actual fight itself was about 2mins.
