5b:T484,

This addon is still in development. It is a port of my old RegenFu addon from vanilla.

You will need an addon such as TitanPanel to host this for the time being.

Shows your HP/MP regen rate, and tracks mana regen 5 second rule statistics.
Min/Max HP/MP Regen Rates
Current HP/MP Tic
Last/Current fight time in mana regen
% of regen time inside the 5 second rule
equivalency ratios for int and spirit to mana5
Multi-fight mana regen data accumulation
Click the text on the bar to unlock the 5SR bar and move it around

Still Todo:

Localizations
~~5 Second Rule Countdown Bar~~
Improve tooltip look and feel
~~Options Menu~~
Possibly integrate tech from my ManaMetrics experimental addon
