It's not recommended to use any macros on either healer because you can't queue macro abilities which causes them to be used a bit slower than they would be without macros (for example, if you're chain casting Physick without a macro, you can queue the second cast 0,5 seconds before the first one finishes, and the second cast will start as soon as the first one lands, while when you try the same with a macro, you need to start casting the second one after the first one has landed which will cause a small break between the casts). This is a problem with macros in general and applies to all actions. Additionally, Embrace has a different recast time than your heals, which means trying to cast them always at the same time (in same macro) will cause you to skip some Embraces.

The only macro I've used on my healers is Virus on focus target when I want to use it on a boss or another monster while I need to stay focused on healing a tank, for example. But I haven't used it either since Turn 8.
