I am having some trouble setting up my mage/hunter combo properly. (mage is my main)

more specifically I am having a hard time with autoshoot on my hunter. Should autoshoot be set to its own key, or should I just try to avoid it all together and use a spell like arcane shot to invoke autoshoot?

Also if anyone else has any experience playing a mage\hunter combo and has some helpful tips or macro ideas I would be very grateful if you would share them.

Thanks,

Steven
