Do not touch Slate dragon and make sure your tanks are taunting off each other once they reach around 8 or so stacks of the healing debuff.
Also make sure the tanks debuffs are cleared before they taunt off from one another.
After Storm and Whelps are dead Bloodlust and nuke Halfus before he enrages, at this point it's pretty much a tank and spank as long as your tanks continue to taunt off each other and the interrupt rotation continues.
Make sure your raid is closed to topped off for his chain stuns.
