Ok first of all let me say been tossing and turning for 2 hours because ive been thinking about this and cant sleep too lol. Also tried it for a short time not in an instance or pvp just running around killing mobs seeing how it works, and i love it. This is what i do. I add a keymap for my f8-f12 buttons ok. Next i make a macro for each button and bind it. Each macro just says /target toons name. After that all i have to do is hit 6-0 for w.e. heal i want to use. Oh snap another toon is in trouble hit say f9 i target that toon and give him a heal and so on and so on. Ive been testing it with my lock team and priest atm. Now i can just sit in a turtle spot and pop shield on each and a rejueve and dot dot dot life tap dot dot dot. If they really get in trouble i have circle of healing or greater heal. But for now the bubble holds long enough to get some dots off and a rejueve so that my toons can life tap at ease. Only toon that needs food now is priest. But with priest having good mana regen and 3k more mana then the locks i can go awhile without drinking. So if you want go ahead and try this way. I found out its better then click healing or making toons of healing macros. Just make 5 macros saying macro one /target toona macro two /target toonb and so on. Then like i said bind each one to f8 for toona f9 for toonb and thus. Then all u have to do is fight and if u hit those f buttons only your healer will target someone different and you can feel free to heal heal heal.
