I have my tank on the main screen and have a repeater region over the party frames which broadcast to my healer for healing, my mage for decursing etc. That only works if each toon has their frames in the same order, otherwise your healing someone else. Super simple to setup with vuhdo, just prefer the look of elvui and the fact that I could do without an other addon. I've tried the official forums and the help I got there didn't really accomplish anything. i've switched back to vuhdo for now until I can sort this out.

thanks though
