7.25 GS macro for mage tier kit

Good evening all, i have been looking at my burst macro and how to place this into a GS version. I have done this with a few minor changes. The macro listed below is a work in progress and if anyone has any ideas to improve it please let me know. Hope you all enjoy.

Sequences['Arcane_burst_new'] = {
-- This Sequence was exported from GSE 2.1.03.
  Author="Origin@Mazarigos",
  SpecID=62,
  Talents = "2123131",
  Help = [[This GS macro is designed with the new tier kit in mind]],
  Default=1,
  MacroVersions = {
    [1] = {
      StepFunction = "Sequential",
      KeyPress={
        "/targetenemy [noharm][dead]",
      },
      PreMacro={
      },
        "/cast !Prismatic Barrier",
        "/cast [nochanneling:Arcane Missiles] Mark of Aluneth",
        "/cast [nochanneling:Arcane Missiles] Presence of Mind",
        "/cast [nochanneling:Arcane Missiles] Arcane Power",
        "/castsequence [nochanneling:Arcane Missiles] Arcane Blast, Arcane Blast, Arcane Blast, Arcane Blast, Arcane Blast, Arcane Barrage, ",
      PostMacro={
        "/targetenemy [noexists][noharm][dead]",
        "/cast [nochanneling] Arcane Missiles",
      },
      KeyRelease={
        "/cast [nochanneling:Arcane Missiles] Rune of Power",
        "/cast [mod:alt, nochanneling] Arcane Missiles",
      },
    },
  },
}

The actual burst macro i use that isn’t GS is as follows:
You will need Macro tool kit at its extended lines to use.

/targetenemy [noexists][noharm][dead]
/castsequence [nochanneling]reset=15 Mark of Aluneth, rune of power, arcane power,Presence of mind, Arcane Blast, Arcane Blast, Arcane Blast, Arcane Blast,Arcane Blast, Arcane Blast,Rune of power,Arcane Blast, Arcane Blast, Arcane Blast,Arcane Blast, Arcane Blast, Arcane Blast,Arcane Missiles, Arcane Missiles, Arcane Missiles, Arcane Barrage,
