This is not the correct sequence.
1. Curse of the Elements
2. Potion of the Jade serpent
3. Dark Soul: Misery [If you have a on use trinket then you need to macro Dark Soul+Trinket]
4. [Macro]: /cast Soulburn /cast Soul Swap
7. Malefic Grasp
8. Maintaining DoTs: This is Mists of Pandaria and not Wrath of the Lich King thus we clip our dots as close to the end mark as possible. Make sure all DoTs are kept up as close to 100% you can let haunt fall fully off before reapplying it onto the target.
Stop spreading misinformation, if your going to call him out for giving the "wrong starting sequence" you could at least post the right one ffs.
Among other things you DONT doomguard in the opener, you save it for Sub 20%
