Is your feature request related to a problem? Please describe.
I would like to trigger a weakaura when 3000 mana is missing to be able to use a mana pot as early as possible in a fight.

Describe the solution you'd like
Under player info>power>mana I would like a deficit trigger that triggers when x amount of power is missing.

Describe alternatives you've considered
Alternatives involve using % based or absolute power triggers, however with changing buffs etc these are not able to provide an accurate trigger at 3000 mana deficit.
