Let's see here.. i use a basic 3-in-1 for my heavy swing as follows
/micon "Heavy Swing"
/ac "Mercy Stroke" <t>
/ac "Heavy Swing" <t>
/ac "Tomawhawk" <t>
Serves same basic function as yours, just removes MS from the list of ones taking up space too. Have a basic simple /wait 3 for all 3 basic combos (BB/SE/SP) with second and third hits in them, no need to type that simple out. Have a macro for zerk to warn the healers to remove pacification after 20sec, as follows..
/micon "Berserk"
/p <Berserk> <Just used it.> <Esuna>/<Leeches> <Ready!> In 20sec for <Pacification> <Please>! <se.7>
/ac "Berkserk" <me>
Only other one i use is just a simple holmgang one to give warnings so people know if they will have to instantly top me off or they have a moment to dodge mechanics before i need bombed with heals.
