Welcome to the Paladin guide!
The Paladin is for many a holy class that allows you to RP the crusader you always wanted to be!
The Paladin offers quite some utlity such as a full heal and a shield. It's able to burst greatly in PvP but has a low AOE for PvE.
Tanking got killed in 10.0 when Warrior took over, but it's going to be a thing again once 14.0 starts.
The Paladin plays DPS aspect in both Pve and PvP, and is a quite tanky force to recon with when he's on the enemy sidelines.
It's one of the 4 Tank classes in the game and thus has the same utlity toolkit as the other tanks.
In Tank aspect, it focusses on metabolizing its damage in its barriers whilst holding threat.
Using the damage in its barriers, it can do certain abilities based on that damage.
