/cast @target

So im a bit lazy and that is why we are all here aint it?.
well is it a way for me to do a /cast target macro for blizzard. so i just have to push the button, and dont worry about where my cursor is and have it cast at my current target??

Here’s something to get you started…
/cast [target=focus,exists,nodead] [] <your spell here>

For interrupts i like to precede it with stop cast, so it goes right away

/cast [target=focus,exists,nodead] [] <my interrupt>

Since you mention where the cursor is i suspect you’re asking about the Radials like Earthquake and Death and Decay?

If so then no, you can’t use @target conditionals for those abilities.
For those only @cursor or @player have been allowed.

it was for my blizzard on my mage, but would it work with /cast [target=focus,exists,nodead] if i have the boss as a focused target ?

Sadly not, any AoE that you have to place with your cursor will only accept @player and @cursor conditionals. @target would be nice but i guess Blizzard deem it maybe too powerful to have it macro’d
