Below are a few of my hunter macro's i use, most of them are for PvP but some can be used for PvE.

I have this in slot 1. If you go into key bindings in the main menu, bind it to a mouse key. (i use a thumb button on my mouse)

/cast Auto Shot
/script PetAttack();

This is needed by all hunters who PvP. You have to spam the macro for it to work. I find that using insignia of the horde, running a short distance then spamming means a 100% chance of a freeze trap. Also i have found you need to stand still for a short while when spamming, for the trap to go down.

/script PetFollow();
/script PetPassiveMode();
/script ClearTarget();
/cast Feign Death
/script SpellStopCasting()
/script CastSpellByName('Freezing Trap')

Get rid of raptor strike and wingclip out of your action bars and replace with this. You will want to take wing clip out when fighting PvE as it will use up mana.

/Cast Wing Clip
/Cast Raptor Strike
/Cast Counterattack
/Cast Mongoose Bite


Another interesting macro, it checks wheater your target has any mana and fires a viper sting if they have no mana it uses a scorpid sting. I dont use this macro though as i find its far easier to drain a casters health than it is mana, the only time i use viper stings are against palidins to stop them bubble shielding.

/script if UnitPowerType('target')>0 then CastSpellByName("Scorpid Sting(Rank 6)"); else CastSpellByName("Viper Sting(Rank 2)"); end

Add your own macro's below to help all the hunters out there ^_^
