Adapted from TimeToDie, this add-on attempts to show how long it will be before you run out of mana.
Currently this may be a bit rough, as it uses mostly the same algorithm as TimeToDie did. Since mana is more fluid (many players gain mana periodically during combat), we may want to work on a more complex algorithm. Any feedback is appreciated.
This was a very quick adaptation so let me know if there are any issues. It has not yet been tested in a raid environment.
Many thanks to Mecdemort for the original TimeToDie.
