Players have the option choosing a Tank Class and becoming Warrior, Paladin, Dark Knight or Gunbreaker, with each role fulfilling a different set of advantages that might put them in a better position than the others depending on the content. However, like with many games, there is no determined best Tanking job, as the flexibility to play whatever you want is quite prevalent in this specific MMO.
At the beginning of the game you can only choose Marauder and Gladiator, which each turn into Warrior and Paladin respectively at level 30.
Dark Knight can be unlocked once you enter the first expansion, Heavensward, and starts at level 30.
Gunbreaker can be unlocked in the base game whenever one of your jobs reaches level 60, and starts off at level 60.
