Holy Paladin Healing Macros and Addons — The War Within (11.0.5)

With the release of The War Within, you were given the option to enable mouseover casting. This will cause your abilities to heal whoever your cursor is currently hovering over when you press an ability. This will save you from having to create many mouseovers for each ability. Keep in mind that many players will need to disable the "auto selfcast" setting once enabling mouseovers; otherwise every spell will be cast on you.

ElvUI is a complete replacement of the default User Interface. It comes with almost everything you need to perform properly: action bars, unit frames, cooldown timers, proc displays, etc.

Boss mods are addons that warn you about boss abilities and give you live advice on how to handle some mechanics. We strongly recommend you to get one such addon. At Icy Veins, we mostly use Deadly Boss Mods, the most popular boss mod. A good alternative is Big Wigs.

GTFO is a lightweight addon that notifies you when you are standing in harmful effects or when you are making other such mistakes. It is very useful, even if your boss mod is already alerting you of such things.

Parrot and Mik's Scrolling Battle Text are highly customisable addons for displaying floating battle text while in combat (incoming heals, damage of your spells, etc.). They both work very well by default.

Recount is a well known addon that most people use for displaying current DPS or HPS (Healing Per Second). This add-on is not really lightweight, and provides a very high amount of information (and it can sometimes cause issues with performance). It is generally a good option to use Recount for checking what you take damage from and if the share of damage/healing you do with each of your abilities is similar to that of other players of your class.

An alternative to Recount (similar in function, so the choice is personal preference) is Details!.

A lightweight alternative to Recount and Details! is Skada Damage Meter.

Raeli's Spell Announcer is an extremely useful addon that allows you to send announcements whenever you use certain spells. It is of particular use to announce when you use raid cooldowns or other important abilities.

Method Raid Tools is a useful addon that allows you to track the cooldowns of other raid members, as well as providing you with a wealth of other useful raid information.

Vuhdo is a highly customizable alternative to mouseover macros and default raid frames that can provide greater functionality, such as allowing spells to be bound to mouse buttons, among other things.

WeakAuras is an extremely useful addon that allows you to have visual effects on your screen, helping you track your buffs, debuffs and cooldowns. It is highly customisable and it can make it much, much easier to keep track of your procs and play your spec more proficiently. It can also be used for a variety of other functions.

If you are looking for Holy Paladin-specific WeakAuras Wago is an excellent place to start. It has many different WeakAuras created by experienced users that can track and display just about any information you might need.
