healing macros

[bandizzzle 0]

I'm using THIS macro:

#showtooltip Rejuvenation
/cast [@mouseover,help][] Rejuvenation

It casts on my mouseover target, but if I have no mouseover target, it heals my target.

How would I go about making a macro that does the opposite? Heals my target, but if I have no target heal mouseover target.

Any help would be appreciated.

Imo that would be terrible.

Having a consistent healing technique is a plus, meaning I personally heal almost exclusively with a mouse over (vuhdo, grid whatever heal frame you're using).

This remove all the possible surprises, where you thought you were healing A, but was actually healing B.

You want:

/cast [@target, nodead, help][@mouseover] Rejuvenation

This casts Rejuvenation at your target if your target is friendly and alive, and at your mouseover otherwise.

I never understood the reason for all these complicated macros.  I've simply used 

/use [@mouseover] Rejuvenation

to great effect.  Sometiems when I want to add more than one spell I'll do something like this:

/use [mod:ctrl, @mouseover] Ironbark; [@mouseover] Swiftmend

That's really all you need.  Next 'complicated step' is if you want to do something if you're mousing over an enemy instead of a friendly in one button
