That one is from a guild that I would say is roughly 2 weeks ahead of us. Maybe a bit more. Some good tips in there, one of which is to have tanks more dps speced, glyphed, and trinked.

But on that note I found this video shortly thereafter that had an idea that near mindfucked me in it's simplicity.\

Pharamones are similar to how we do (they swap at 15) but instead of their normal 2 tanks, one tank goes full out dps and their Frost DK goes blood spec (still in full dps gear) so he can help by healing himself a lot and in turn help healers. It seems most of the strats I find are Tanks in tank spec but with full or partial dps gear on to help beat enrage

That above video has a tip for Pharamone kiters

Move slow with the paramones if he's far from you, and fast if he's close. and don't stop moving even for a second, because if you're in a pharamone pool during a crush, well it's GG

Another one is to have range focus hind legs down first and keep that as a priority, let the tanks/melee handle the fronts as they will get the bonus to cleaving them as well as focusing one down

Other than those tips we have the strat we need to kill him
