Paladins are not just Paladins. We have many names, Critadins, Waradins, Retnoobs, Clerics, Healadins, Tankadins, the fact of the matter is that we are the most durable class and can adjust to play in any situation, and only you can decide what type of Pally you want to be.
For those of you looking to play a Healadin, Holy is the talent spec to go with. In raids, everyone who can heal, naturally heals. A Paladin fits into this natural order by staying back and healing, and thanks to their ability to wear plate, can be one of the most dangerous healers in the raid group, if they're played well enough. Perhaps reading this guide will simplify for the work you need to extort while playing your Healadin.
Plate Priest, Healadin (30/21/0)
This talent spec focuses on the talent trees, Holy and Protection. The Holy part of things gurantees that you will be far more substantial at healing during raids, and the additional buffs of armor, defense and the new blessings from the protection tree combine to create a build very good for healers who can live out during the raid, and absorb damage. for Paladins very rarely end up using the same build, although many times they are similar. After speaking with many Paladins, it has been easy for me to determine this as one of the premier builds for a Paladin, as the bonuses to Intellect, the addition of two of the most important blessings (Sanctuary and Kings), as well as the Improved Blessing of Wisdom Buff, makes this a great build for a Healadin looking to be very active during raids.
Reckonbomber, Tankadin/PvP (5/34/12)
Reckonbomber is the PvP spec that I most recommend to Paladins, as the Imp Hammer of Justice, Reckoning, and Holy Shield make you a force to be reckoned with, as a Paladin with four reckoning charges, Seal of Command and a Kings or Might Buff can easily kill in one hit many of the people which he or she faces. Tankadins have Improved Righteous Fury and Holy Shield to contribute to a rough 110% increase in threat cause, which helps them to pick up a great amount of threat, and manage it much better than the Holy alternate tank path.
====Holy Tank, Tankadin (31/20/0)
Holy tanks are very good at grabbing initial agro thanks to consecration and Holy Wrath, which can act like a warrior's taunt, and immediately try and gain snap agro from someone if they manage to steal it from the Tankadin. Holy paladins, using Imp Righteous Fury can have a great chance of gaining agro with Holy Wrath, allowing them to deal a great amount of threat when in order to quickly get their targets.
Retribution spec'd Paladins typically fall under the name Critadins, as they attempt to do what many think is an oxymoron: Paladin DPS.
Heavy Ret, Critadin (5/8/38)
This spec's main focus is on the Retribution Tree, although it invests in the early talents of the Holy Tree and Protection Tree to gain both a strength and armor bonus. This build is meant for Paladins who are more interested in dealing damage rather than playing a great role in a group or in PvP. While this build does have its weaknesses, it does make the Paladin have a much greater chance to be a threat on the DPS scales.
