Some essential macros for Marksman Hunters in arena. Notice that some are not useful outside arena.
Focus Fire + Trinket
/cast Rapid Fire
/cast Roar of Recovery
/use Ruthless Gladiator’s Badge of Conquest
Chimera Shot (most of the important abilities should get the /stopcasting macro because casting a steady shot (being in the middle of the cast) when you have Kill Shot ready is not an option
/StopCasting
/StopCasting
/StopCasting
/cast Chimera Shot
/script UIErrorsFrame:Clear();
(the same goes for Aimed Shot, Kill Shot, Deterrence, Silencing Shot, Scatter Shot, etc.
Scatter Shot + Trap Launcher on focus (you focus an enemy in arena by right clicking on his icon, you won’t have to select it when scattering). Also if you have no focus, the macro will cast Scatter Shot on your current target. Same for Silencing Shot.

Chimera and Aimed Shot cannot use this macro as they have cooldowns.
