Problem was we both did the stacking debuff and hit us tanks at 100% attack speed; we stacked 10 debuffs in less than 15 seconds which is completely unmanagable, since the debuff has a 30 second duration.
Our solution was to have me (Protection Warrior) pull Halfus and pull him towards the Nether Scion, which our Pally tank freed. Our Hunter also freed the Storm Rider and MDed him to the Pally. The raid immediately popped Heroism and nuked the Nether Scion. Our Shaman was now able to interrupt the novas with a focus macro, and tank swapping was managable. (When I had 10 stacks, the Pally taunted Halfus and I taunted the Nether Scion. The Paladin then cleared his stacks at 15+ with Divine Shield and took another ~10 before we switched again. As my stacks wore off, I taunted the Storm Rider and we burnt it.)
Then all we had to do once the dragons were down was to survive his aoe shout, which was cake with 3 healers.

There are 5 dragons. Every week, 2 dragons are asleep, which 2 are chosen by server RNG. I'm not entirely sure what all dragons do yet, but last week the Slate Dragon was asleep, rendering him unusable. Since he was asleep, the boss didn't have his stacking debuff. If the Storm Rider is asleep, the boss won't use his Shadow Nova.
If the Storm Rider isn't asleep, the boss has a 0,3 second cast raid wide knockback nova every 6 seconds. If you free the Storm Rider, the cast time is increased to 1,5 seconds.
