Fast Attack Macro

This is a macro that I use to attack mobs quickly with my pet, but with no loss of damage due to not taking the time to cast a Hunter's Mark:

/Cast Hunter's Mark
/petattack

I then bound this to the same key that Hunter's Mark was bound to previously. There are very few instances where a mob that my pet attacks is not going to be shot at as well, so this is much more efficient than doing the Mark and Pet Attack separately. Even better, when my pet is on "Stay" (as in cases where the boss would easily kill the pet with AOE damage) he does not attack the target; all I get is a Hunter's Mark on the target, and I can start shooting.
