Unholy PVP 5.4

Working on a UH pvp macro. Basically I just want to run through a rotation and the basic priorities.

What this does is start with COI + Plague Strike, then SS, IT, BB. The only problem is that it doesn’t Necrotic strike enough. Is there a command I can use to make sure for every Death rune I’ll cast Necrotic Strike?

/castsequence reset=target Chains of ice, Plague Strike,null
/castsequence reset=0.5 0,0,0,0,Death Coil
/castsequence reset=0.5 0,0,0,Dark Transformation
/castsequence reset=0.5 0,0,Horn of Winter
/castsequence reset=0.5 0,Necrotic Strike
/castsequence reset=6 Scourge Strike, Icy Touch, Blood Boil, 
/startattack

Another version of this macro is this one. It doesn’t Chains or PS at the start, and Horn + Transform are manual too.

#showtooltip Scourge Strike
/castsequence reset=0.5 0,0,0,0,Death coil
/castsequence reset=0.5 0,0,0,icy touch
/castsequence reset=0.5 0,0,Blood Boil
/castsequence reset=0.5 0,Scourge Strike
/castsequence reset=4 Necrotic Strike, Necrotic Strike, Necrotic Strike
/petattack
/startattack
