Important Weakauras, Addons and Macros

This weakaura will display an icon on your party frames whenever a dangerous spell is being cast on someone. This is essential for any healer who wants to push keys regardless of class, as it keeps you aware of exactly who is being targered by what so you can take preemptive action. This will also draw a red line between you and any mob that is targeting you with a dangerous ability so you can see where you're being targeted from.

Every holy paladin in the world has realized halfway through a fight that they forgot Beacon of Light at least once. Use a weakaura to prevent this tragedy.

ALWAYS HAVE YOUR AURA SET TO DEVOTION DURING DUNGEONS. It's very easy to forget to swap or activate Devotion Aura at the start of a dungeon, which would be disastrous for pretty much any key difficulty. Use to remind you to set your correct Aura in different content (Devotion for raids/dungeons/arenas, Concentration for RBGs, and Crusader for World content).

This is my custom weakaura for tracking Holy Power and Of Dusk & Dawn, great for if you want a custom visualization of your Holy Power.

These are my own custom weakauras for tracking things important Holy Paladin abilities like Wings, HA, Divine Toll, Aura Mastery, etc. Not required but it's definitely helpful!

This is another weakaura I made that checks whether you have food, flask, armor kit and weapon oils applied.

This is my personal weakaura that simply adds a loud sound effect to any frontal that happens in a dungeon. For those who find audio cues helpful this is a very lightweight weakaura that will help ensure you never die to the most dangerous avoidable mechanics.

Spell cooldowns are especially important for healers to know when damage is incoming. Use this weakaura to display the internal cooldowns of trash mobs' major abilities next to their nameplates.
