Lvl 80 pally

Build a Holy spec with Denounce, Eternal Glory, and maybe Blazing Light. Technically, you can use a spec like this for group healing as well but I would recommend using it as a second spec outside of dungeons. Then practice your DPS rotation while leveling & questing. Use Concentration aura for pushback resistance and keep Inquisition up as much as you can.

This spec will make it a ton easier to get to 85 as Holy though it will never get you there as quickly as Ret or Prot. Denounce is the most important component as Exorcism is hideously expensive at higher levels but you will need to spam it to do even laughable damage.

This spec & method is a stepping stone to Ret/Prot gear through quest completion or a slow grind best coupled with a gathering profession and dungeon healing. At 85 this spec is good for laughs in LFR. If PvP is your thing, note the 2v2 specs at Arena Junkies match the basic requirements.
