Need Macro Help - occasionally cast on self

[Elvenbane-veknilash (Elvenbane)]

@Elvenbane-veknilash

Heart of Azeroth Essence Macro

Alt: Self Cast
Mouseover: Cast on Mouseover
Reticle: Cast at Cursor (while in combat)
Default casting behavior. This condition also serves to generate the correct tooltip.

#showtooltip
/cast [mod:alt,@player] [@mouseover,exists,nodead] [@cursor,combat] [] Heart Essence

Trimmed and adjusted.

#showtooltip
/cast [mod:shift,@player] [] Heart Essence
