Your dps need to step it up looking at that log, top ones barely pulling 7k at 30% and your tanks are mixed in with the dps. for the tank flame moving plan it out ie we start from far right and move 3 times to the left and then rinse repeat, everyone stacks behind marrow for bonespikes. if people run to opposite ends of the room in bonestorm phase and get spiked then replace them in the raid they are causing problems. use raid cooldowns in bonestorms, tanks use a cooldown when he comes out of bonestorm and get him into place ASAP.
Marking targets, coordinating CC, and *most importantly*, pulling responsibly so that 9 elites didn't rush us and wipe the party, this Is something I have missed since nov 08.
