FDHealth

A feigned hunter's health cannot be read directly, because the API returns zero for UnitHealth("Player") once FD takes effect. To work around this, FDHealth:

Snapshots current health immediately before FD
Simulates regeneration based on your spirit
Monitors combat log events to adjust for damage and healing

Uses a standalone, configurable bar for simplicity and to avoid compatibility issues with unit frames.

Updated for TBC but it appears to be redundant as health is now visible in the player frame while feigned. Still relevant for Classic.

Configuration

Notes

Designed to be lightweight and accurate enough within typical use.

Accounts for the troll racial bonus, both in and out of combat
HP5 is not factored, as it is uncommon and has minimal impact
