I think about it have castsequence for several targets, like castsequence [target=focus] Rejuvenation, Lifebloom,Lifebloom, target[targettarget] Wrath or something else, wich get possible cast heal inside dps macros.
Is it can be done using Jamba macroses? Or how its work then?
You should consider macros which use modifiers: Shift/Ctrl/Alt
If dedicated DPS should cast heal spell I usually do it by using another keybind, not to put every thing under DPS sequenc
