HealRec - Classic Era

Introduction

This is a classic version of https://wago.io/fzyHZcOw0. Thanks to BLZ making available of the API UnitGetIncomingHeals, this WA is now usable in WoW Classic Era.

This simple WA suggests the healing spell & rank according to unit health deficit, accounting incoming heals. The incoming heals cannot factor HoT heals currently (see https://wowpedia.fandom.com/wiki/API_UnitGetIncomingHeals). An icon of the spell & rank will be displayed on the top left corner (by default) of the unitframe .

How to use it:

• Import the group from website.
  
• Open 'Custom Options' tab, where you will find some toggle options and a Flash of Light overheal threshold Y. The toggle options KBHLX and KBFoLX are on/off switches for users to indicate if they keybind Holy Light(rank X) and Flash of Light(rank X) and monitor them. Check KBHLX if you keybind Holy Light(rank X) and similarly for FoL. The FoL threshold controlls the minimal amount  of health deficit of a unit to trigger Flash of Light recommendations. FoL triggers are equal to the threshold Y * the amount of FoL spells.
  
• Start using it.
  

Warning:

Although there is potential to make the icons clickable, it is NOT recommended. Clickable WAs are notorious for breaking during combats. They also can irreversibly mess up your other WA settings!
Plus I do not have any intention to reincarnate the original Healbot within weakaura. Again, I do not recommend doing it, and I will not be responsible for any outcome from doing it.

Now, please enjoy your time playing with it.
