Dwarven, how many times are you spamming the button before your multicasting software (HKN for me) tells a new signal? I'm pushing "d" the entire time, a few times a second. With your solution, if you mistime your spamming you will cast two rejuvs on the same target before switching. The reason the macro I posted before, with many nils at the end and reset on target, works is because you can spam it as much as you want and it will only cast that new rejuv when the target changes.

I'd like others to test their solutions and see if they'll really work. I spent at least 4-5 hours on this problem and I think I've tried every solution posted in this thread, already, but I could be wrong.
