Oomometer?
 

Not sure if anyone has ever made an addon similar to this or not, but if someone is willing to attempt this idea I'd love to pitch my ideas and "help" as best I can.

Basically the idea is similar to "Time to die" giving an estimated time until being OOM.

Calculations involved could include mu5 (mana used per 5), mp5 (natural regen), pure mana gained (via skills, potions, and otherwise), etc.

Anyone have feedback to this idea? Has someone taken the effort?

Would you find this addon useful?

Something like TimeToOom?

yeah except it'll work

that thing never works for me. just shoots out random numbers that make no sense.

cast mind blast it tells me 45 secs cast flash heal tells me 2 mins, cast refresh tells me 30 seconds.

no much help imo

but i would love an addon like that, that would actually work lol

Nothing will work on trash and fights in general that end sub-1 min.

That's not to say this particular addon cannot improve but addon such as this makes more sense in the typical 5min bossfight.

Since the release of WOTLK mana costs are based off a percentage of your total mana pool. Just take your total mana and divide it by your spell cost.... Atleast thats what I do as a healer to know I can cast Healing Wave, Lesser Healing Wave, Chain Heal x amount of times. Of course this does not include mp5 and regen trinkets, riptide crits, buffs, mana tide, and 4 piece t10 bonus.

Adding links to a couple more attempts.
Note: I don't use any of those addons myself so cannot advise on their functionality.

- GNome Out Of Mana
- ManaWatch

Base mana, not total mana.
