What spec and glyphs should I should I use as a Holy Paladin for raiding?
That is a good question and really depends on how you want to play and what your role is in the raid. Currently there are two prevailing specs and each have their plus and minuses.
The first spec is the Flash of Light spec (51/5/15) which focuses on a bigger Flash of Light (FoL) heal, more mitigation via Sacred Shield (because Sacred Shield scales with Spell Power), increases the HoT effect of your Infusion of Light talent, and relies more on your healing spells to crit. The problem with this spec is that if you are not mostly using FoL you’re going to have to watch your mana pool closely because Holy Lights and Holy Shocks are going to eat through your mana pool.
This spec also greatly benefits from the four piece bonus of the T9 set which increases the HoT of your FoL by 100%. The major glyphs I would recommend if you are thinking about using this spec are Glyph of Seal of Light, Glyph of Beacon Light, and Glyph of Flash of Light.
Glyph of Seal of Light is a flat 5% increase to your healing spells and since you will be criting more with this spec (which means more mana being returned) you won’t have to worry about your mana as much, which means this glyph is going to benefit you more than the Glyph of Seal of Wisdom.
Glyph of Beacon of Light is chosen because it is going to add 30 seconds to Beacon of Light which means you don’t have to worry about it dropping off your target as quickly. In addition you won’t have to worry about trying to cast Beacon of Light and Sacred Shield (both have a 30 second durations) at the same time, it will also conserve some mana because you won’t be casting it as much, and plus it will let you focus on using your healing spells more.
Glyph of Flash of Light is a must have for this spec. It increases the crit chance of your Flash of Light by 5% which calculates out to a 1.5% mana return and a 2.5% increase on your Flash of Light heals.
If you are going to be the main tank healer in a 10-man or 25-man ICC raid I would suggest against this spec, you’re are going to be clicking FoL so much you may break your mouse. There are two situations when I would use this spec. The first is if this is my off-spec and I was running a 10-man or 25-man and if an extra healer was needed, I would step in. Between your Beacon of Light, Sacred Shield, and FoLs, this should give the other healers in your raid the buffer area they need to keep everyone topped off.
The other situation I would use this spec in is if I was backing up the main tank healer or helping with raid healing in a 25-man raid. Your FoLs will be filling in the gaps of the other healers and help keep everyone topped off.
EDIT: Forgot to mention there’s a part 2 coming
