Nola asked me to post some macros, so here are a few shot macros I'm using for my new MM spec:
#showtooltip Aimed Shot
/cast !auto shot
/cast Silencing Shot
/cast [target=pettarget,exists] Kill Command
/cast Aimed Shot(Rank 9)
/cast !auto shot
/cast Silencing Shot
/cast [target=pettarget,exists] Kill Command
/cast Multi-Shot(Rank 8)
#showtooltip Kill Shot
/cast !auto shot
/cast Silencing Shot
/cast [target=pettarget,exists] Kill Command
/cast Kill Shot(Rank 3)
#showtooltip Chimera Shot
/cast !auto shot
/cast Silencing Shot
/cast [target=pettarget,exists] Kill Command
/cast Chimera Shot
/cast !auto shot
/cast Silencing Shot
/cast Serpent Sting(Rank 12)
/cast [target=pettarget,exists] Kill Command
#showtooltip Steady Shot
/cast !auto shot
/cast Silencing Shot
/cast [target=pettarget,exists] Kill Command
/cast Steady Shot
I also have a couple SV specific ones:
#showtooltip Black Arrow
/cast !auto shot
/cast [target=pettarget,exists] Kill Command
/cast Black Arrow
#showtooltip Explosive Shot
/cast !auto shot
/cast [target=pettarget,exists] Kill Command
/cast Explosive Shot
So the !auto shot forces the auto shot before the cast of the special shot. However, I cannot take credit for any of these. I got them off of Kripparian's youtube page and I highly recommend watching this ten minute video on macros and keybinds:
