Request: "Smartcast" for Ground AoEs

[Morrigu]

I know this isn't 100% what you're looking for, but you can sort of macro it to drop at your feet, or centered on the tank.

/ac "Earthly Star" <me> (at your feet)
or
/ac "Earthly Star" <2> (if your tank is in the 2nd slot, change the 2 to which ever slot your tanks in, also can use a players name if you work with a raid group etc.)
or
/ac "Earthly Star" <t> (if you're targeting a mob to place it centered on the mob)
you can also use this on other ground aoes

for instance for DRK
/ac "Salted Earth" <t> (will drop it on your current target, but only if the target is in combat)
