Thanks Griznah but nope, still same behavior with that script.

They fire once and only once.

I've discovered the same problem now with Drain Soul. They begin drain soul for .5 second and then stop. The only way I can make either work is doing an assist first to give them the target -- but that screws up everything and completely negates the 'targetless' strategy, and adds an extra keystroke in between each fight.

Thanks for more ideas, I hope I'm doing something wrong, or its a config thing in the blizz client.
