I'm well aware of the usual shot/AotH macros hunters use, but they are not perfect. The goal of these macros was to cut keybindings and maximize dps.
/cast Arcane Shot
/cast Steady Shot
The macros just feel clunky and I hate them.
My alternate approach: One macro'd key to switch freely between all three interesting (hunter) aspects in PvP combat.
/castsequence [nomod] Aspect of the Hawk, Aspect of the Fox
/castsequence [mod:alt] Aspect of the Cheetah, Aspect of the Fox
If you press alt modifier as well, you will end up in Cheetah. Useful, if you just disengaged and want to use the 60% sprint of Post Haze talent (MM) and you know, you won't get hit in that time (Deterrence, BoP, LoS).
