Brewmaster 7.3 casual player

I am a very casual player, and am looking for critique for the most “efficient” script/macro. Please feel free to suggest fixes for what I have wrote. I am sure this is modifications of others scripts, but I haven’t modified them in months, so I won’t remember the originator.

Here is what currently use:

Sequences['brew'] = {
  SpecID = 268,
  Author = "ME",
  Talents = "2,1,3,3,1,1,2",
  MacroVersions = {
    [1] = {
      StepFunction = "Sequential",
      KeyPress = {
        "/targetenemy [noharm][dead]",
      "/cast Blackout Strike",
      "/cast Keg Smash",
      "/cast Rushing Jade Wind",
      "/cast [combat] Ironskin Brew",
      "/cast Breath of Fire",
      "/cast Blackout Strike",
      "/castsequence Keg Smash, Rushing Jade Wind, Breath of Fire, Purifying Brew, Ironskin Brew",
      "/cast Tiger Palm",
      "/cast [@player] Exploding Keg",
      "/cast [combat] Leg Sweep",

**NOTE: Feel free to replace “Leg Sweep” with any other tier 4 talent (i.e. Summon Black Ox Statue)
**NOTE: I use the legendary shoulders, and just have a macro for that number key with Keg Smash (i.e. 5)

FYI, I will be submitting the same request for critiques for each class/spec I play. Thanks!
