Nostalrius Begins - Quality wow vanilla realm (1.12)

Any specific Addons or Macros you really can't play without?
It would be nice if we could compile a list of addons which we find essential for Priests

I'm not using many addons. Only a few so far that I found to be helpful for me.

Luna Unitframes got some nice frames for healing. Best part it's still being developed. Most should know about this one by now though.

TheoryCraft is a addon to track your bonus healing, crit %, mp5 etc.

Classic Snowfall will speed your actions up. Your spells are cast on key press instead of key release with this addon.

TnE Fivesec Lets you know when you regenerate full mana following the 5 second cast rule. Appears a little buggy at times.

What addons do YOU recommend priests to use for tracking class mechanics, Buffs/Debuffs, 5SecRule, Shield Absorbs, Cast bar and so on?

Chronometer - Gives timers on all your short duration buff/debuff spells like Renew, Power Word Shield and Shadow Word Pain.

Bongos (Get Bongos option)

Big Wigs

OmniCC

AutoSave

Stopthespam

Luna Unit Frames, Best frames imo.

Ecasting bar

Decursive

Classic Snowfall

Clique

Bonus scanner (Calculates how much your heal will heal for)

Are there any addons that downrank based on missing health? Benecast used to back in vanilla, but doesn't work now. Clickheal will downrank based on mana, but not health.

It seems like SmartHeal can, but I'm having a hard time finding the most up to date vanilla one.

Edit: Found a working SmartHeal. Not as good as ClickHeal, but it may get the job done.
