Tonight in Grim Batol was pretty bad. The drake bombing run was fail, they nuked a million troggs and hit literally EVERY mob that didn't need to be pulled. They then pull when I (the healer) am not even landed yet and proceed to flame me for moving too slow. I remained silent. Takes a full mana pool on each set of trash pretty much because the tank insists on eating the damage and not CCing or popping a CD. We wipe on the first boss because the boomkin stood to close to the edge of the platform and a starfall hit the mob on the other side of the fissure. Next attempt the DPS kill the adds correctly but let the purple one get cleaved by the warrior/DK tank and he enrages and gets the purple trogg buff, we barely kill it from me popping a Pain Supression/Barrier on the boomkin who goes bear and I smite spam him down the final 30k. On the trash to the next boss the DK runs in and some how manages to D&D pull the 2 dragonkin mob, the troggs, and the 4 caster/giant mob all at the same time, we wipe again. We come back and barely scrape through the trash (DPS doesn't interrupt the mind link thing the casters do) and we pull the boss. He chooses his 2H mace so hes encumbered and the DK starts to kite, but he doesn't have that good of threat and the ret pally (who stays on the boss the entire time) pulls aggro and is one shot. Then, after the phase is done, he stands in rocks/fire slag and dies. The ret pally then leaves, and we get a mage from the DK's guild. They then pull the boss again and the mage flames me for not keeping him up when hes in rocks and the DK kites too far out of range and he dies. We barely kill the boss again and my wand drops (the only reason I queue'd for Grim Batol) and the mage rolls on it (Spirit/Haste). He loses by 10 and proceeds to spam open trade to give it to me and flames me when I don't. Finally, since I didn't need anything off the next 2 bosses and I wasn't getting valor points, I angle myself on the very edge of the firepit and lifegrip the asshat mage and he promptly falls off the edge, and I leave.
Moral: Don't mess with priests in Cata in instances that have large falls
