While in no particular order, I have separate macros with grouped abilities:

INTERNAL RELEASE MACRO ICON:
Internal Release
Blood for Blood
Raging Strikes
Hawk's Eye
Barrage

BLOODLETTER MACRO ICON:
Bloodletter
Heavy Shot
Misery's End

VENOMOUS BITE MACRO ICON:
Venomous Bite
Bloodletter
Misery's End

WINDBITE MACRO ICON:
Windbite
Bloodletter
Misery's End

I just listed what's in my macros, but I obviously have them listed in-game just to name a few. My songs each has their own macro with Battle Voice in each one. I also have a hotbar just above the main bar with the abilities that are hidden in each macro so I see when they are ready.
