Is it possible to macro an AOE attack?

I am wondering if it is possible to cast an AOE attack off of a Tank's Target, without using the reticle. ie:

Paladin Tank runs in and grabs all the aggro. Druid and Mage sit back, and then target the Tank, and cast Hurricane and Blizzard on the Tank's target, without using the reticle on the ground.

Is this possible?

The best I can see is parking the AOEers right behind the tank and using keybind scripts to hotkey a mouseclick action to a keybinding. If you find out, let me know - I've got 9 engineers in total, heh

No, it's not possible to do this entirely with a macro, but there are some pieces of software that would make it a bit easier to cast multiple ground targetted AOEs simultaneously - for example, HotkeyNet.

Thanks for the lead, I'll look into this information.

With macro's the best you'll get with that set up...

You could macro the paladin to maybe...
/castrandom Holy Shield, Consecrate

You could macro the mage to:
/cast Arcane Explosion

You could manually target the druid's Hurricane.

With a cast random, it will cast one of the available options. So you'd basically be clicking HS and Consecrate when available and frequently spammed on the paladin about the spell is not ready yet.
But you'd still have both abilities up most of the time.
