Does anyone have a macro Heal/Target a Group Member with the least amount of health
Can’t be done. No macro can know what any group members health is. Blizzard wants you the player making that decision not a mod or a macro.
You have to make judgment in your own. Back in the days, people use Spell (Rank) like in Vannila Classic to heal Party or Raid because Mana Management were an issue If you use Higher Spell Rank
Then its also not possible iwhen the target is under 60% Helth use spell A ,over 60% Health use spell B?
In Retail WoW, spell rank is no longer apply and mana is also not an issue anymore. It’s more about big heal and small heal nowadays.
