Yo, figured I would leave you some information for holy paladins!
Ill start with the most important part, which is cooldown usage. The three most important cooldowns for a holy paladin are: holy shock, holy prism and avenging wrath. Holy shock is roughly on a 4,5 sec CD (depending on your haste obviously) and needs to be casted as often as possible due to IoL procs (ionization of light) as well as the class trinket. Due to a proc called enhanced holy shock, which resets the cooldown on holy shock, a good hpal will be able to get his number of HS casts very high. On a perfect fight you can get down to 1 HS pr 3,5 seconds, but anywhere between 4-4,5 is fine usually. Above 5 means that you are not using it enough. The important thing is that we use holy shock for more healing later, not the healing it does itself, this is very different from the next CD which is holy prism.
Holy prism got a 20 second cooldown, but it is not as important to cast if off cooldown. If you know damage is incoming it is better to hold it 5 or 10 seconds. So you want to use holy prism often, but ideally when you can actually use it to heal and not only build mastery shields. On most fights holy prism will only be able to heal the melee.
The final cooldown is avenging wrath, and any holy paladin worth his salts this tier will use it with the glyph and talent which puts it at a 30 second duration with a 90 second cooldown. It is of paramount importance that the casts off avenging wrath matches up with the damage patterns off a boss. For example on archimonde you would use it so you have it for the 1st and 3rd wrought, 1st and 3rd infernals etc. So you can get as many uses on as good spots as possible.
These are the important cooldown, apart from that there are many other cooldowns that also have important uses. Lay on hands, divine shield, divine protection, hand of sacrifice, hand of protection and hand of freedom are all very important utility cooldowns. The first 4 you should use on almost every fight you do, and then the last two depend on the fight. Hand of protection is very useful on mythic kilrogg to remove the bloodseeker debuff, on mythic council to remove the bloodboil debuff and sometimes to clear aggro of a ranged DPS. Hand of freedom is more niche but can be used on mythic gorefiend if you get hit by spirits and need to get out for doom.
What I have mentioned so far is the fundamentals of playing holy paladin, regardless of talent choices. But there is two ways of playing holy paladin right now, and they are called eternal flame and selfless healer. These two playstyles have what I have mentioned so far in common, but then they differ. Selfless healer got what is probably the most rigid rotation for healers. Im going to start with selfless healer:
The basic rotation is simple and repeats itself where it is Holy Shock -> Judgement -> Flash of light -> X. Where X can be another flash of light, light of dawn, holy light or holy prism. The different rotations depend on what buffs and procs you get. If you get a enhanced holy shock proc the cooldown would change to Holy Shock -> Flash of Light -> Holy Shock -> Judgement -> Flash of Light -> X.
I dont think it is worth me going more in depth into selfless healer, but the most important thing is that almost every single flash of light you cast should be buffed by a holy shock in forehand. It is even worth wasting holy power if you have both avenging wrath and bloodlust active at the same time. Your holy shock and flash of light is vastly more important than your holy power spenders.
The eternal flame rotation is not exactly a rotation but more off a priority list which goes as follows.
- Consume the class trinket proc (Magnifying Light)
- Cast eternal flame (5 holy power)
- Cast holy shock
The rest is essentially just using your cooldown when needed, as mentioned previously.
This might have been more in depth than neccesary on these points but I thought it neccessary to briefly explain it to go onto resources usage, which is holy power for paladins. For EF you never want to waste holy power, it is never neccesary for you to do so and EF is always worth casting. In SH this gets a lot less important and if the choice is between casting holy shock and capping over casting light of dawn you should always do so. These are the only holy power spenders for each spec, you never want to touch light of dawn while specced into EF and you never want to touch word of glory while specced into EF. While onto spells you should not use, neither spec should EVER use holy radiance.
Final thing Id talk about is the IoL proc and mana, which I briefly mentioned in the beginning. Because the way a holy paladin consumes mana is essentially through using flash of light which heals for significantly more when buffed by IoL. For both specs this is the primary way of consuming mana, and if a holy paladin ends with low uses of flashes of light buffed with IoL and ends with almost full mana he is doing something incorrectly.
I might've missed some points, and I might've gone a bit too much in detail on unneccesary points. Either way I hope this is useful for you and that you are able to put up a checkmywow on holy paladins!
Cheers and keep up the good work!
EDIT: Just realised I missed a thing I was going to mention. Firstly, while playing SH judgement is also a high priority spell, and should essentially be used off CD barring enhanced holy shock procs or bloodlust + wings occuring at the same time.
