While since I rolled Death Knights for fun, I simply had to figure out a way to utilize AoE's that you have to click to target

Basically you may have to switch your format up a bit, since mine is kind of funky and someone can hopefully make this cleaner.

First things first.

decide which key on your keyboard you want to act as a left mouse click. I choose something I usually don't type in which is " ; "
Code:
/script SetBinding(";", "CAMERAORSELECTORMOVE")
Now copy/paste that into WoW while in the game
Do the same for this line as well
Code:
/script SaveBindings(1)
There now you've bound your left click mouse to the " ; " key. (The Left Click on your mouse button still does the same thing don't worry!!)
If you ever want to remove this functionality - > /wow/WTF/<accname>/bindings-cache.wtf and remove the entry.

Next step make a macro such as this
Code:
/script SetView(4);SetView(4)
/cast Death and Decay
To explain the view pieces, they run from 1 through 5 and you can actually save to a viewing you like, it just positions your camera in that location so you don't need to worry about how your facing. The second entry of setview moves your camera to that position instantly instead of moving to that angle.
Bind that to a key and simply push the button then press ;
I have mine setup so my cursor stays on top of my characters so when I press it, it throws it down right on top of me.
The cleaner part of this is that I use F9 for the hotkey on my action bar macro, and my n52 has the ; key bound as well, so I push then 1 after the other, or together and poof you've got a targetable AoE without moving to that screen and clicking.

Hope this helps.
