This is being discontinued with 8.0 as there isn't much of a min/max gameplay to FR anymore :(
This aura indicates how much Frenzied Regeneration will heal for, as a percentage of maximum HP.
All of the options can be found in Actions > On Init > Custom:
aura_env.showAbsolute: Set to true to show absolute healing instead of percent.
aura_env.numDecimals: Set the number of decimals for percent display.
aura_env.printHealToChat: Set to true to print the prediction to chat every time you use FR.
aura_env.printSummary: Set to true to print a summary to chat after a boss fight.
aura_env.colors: Add/remove entries in the table to color the text when the prediction reaches certain values.
It takes into account the following:
Damage Taken
Versatility
Guardian of Elune
Wildflesh (requires LibArtifactData-1.0)
Guardian Spirit
Divine Hymn
Protection of Tyr
Life Cocoon
T17 4piece
T18 2piece
Skysec's Hold legendary*
*If you are using this legendary, the numbers may fluctuate quite a bit after using FR. Skysec's Hold HoT doesn't roll over like FR, but overwrites itself and wastes a portion if used in quick succession. The aura takes this into account, which can cause the fluctuation.
