I currently use single button: (developed with Macro Toolkit -> as a single step in ISBoxer)

The damage does not compare to the Arcane Mage nor to the Ele Shammy.

Any suggestions ? (I haven't found any Lock macros in the MoP Macro threat either.

Code:
/mtsx
/castsequence reset=target Immolate,Incinerate,Incinerate,Incinerate,Incinerate,Incinerate,Incinerate
/userandom Conflagrate,Chaos Bolt
/use Incinerate
/startattack
/use [combat]13
/use [combat]14
/use [combat]Dark Soul: Instability
/use [combat]Blood Fury
/mtce
/mtso
