Rotation for Demonology Warlock Wotlk

Demonology Warlock Priorities

Shadow Bolt (Keep debuff on boss) > Metamorphosis > Immolate Aura > Curse of The Elements/Curse of Doom > Immolate  > Corruption > Shadow bolt or Incinerate [Molten Core] > Soul Fire on 35% HP

Tips

Keep Immolate, Corruption and Curse of Elements/Doom on the target if the fight is lasting for more than 30 secs, on burn phase depending if the fight is going to end quickly or not Corruption can be kept for [Molten Core], however, if the fight is about to end it’s better to spam Soul Fire.

At the end of Immolate, Corruption can be cast without occurring GCD, this is true for every cast/instant sequence, should be used to maximize DPS.

On most boss fights it’s worth to pop Metamorphosis on the beginning and again towards the end, depending on if the fight is 2 mins longer or not if it’s below 2 mins save it for other CDs like Bloodlust.

Use CDs when there is barely any movement or crowd control effects to maximize DPS, the best way to do this is by knowing the fights and use gateways to minimize movement.
