Dualboxing combo?

Use a Cast Sequence macro, as Demo you would do something like

/castsequence Corruption, Immolate, Hand of Guldan, Soul Burn, Soul Fire, Incinerate, Incinerate, Incinerate, Incinerate

I am not sure of the number of times you would need to cast Incinerate but you get the idea

Same with the mage,

/castsequence Arcane Blast, Arcane Blast, Arcane Blast, Arcane Blast, Arcane Barrage, Arcane Blast, Arcane Blast
