Reprisal is a major part of tank's identity. It's one of the things I love most about tanks. It's one of the most versatile abilities in the game.
  • You can use it to mitigate a raid-wide AoE.
  • You can use it to mitigate AoE markers that every party member has.
  • You can use it to mitigate double tank busters that affect both tanks.
  • You can use it to mitigate raid-wide DoTs.
  • You can use it to mitigate a tank buster on yourself.
  • You can use it to mitigate heavy-hitting auto attacks by the boss.
  • You can use it to reduce the damage the boss is dealing to non-players, such as an NPC or object that you are meant to protect ie. Estinien before the Aery revamp or pillars in A11S.
  • You can use it on trash packs or multiple bosses since it was changed into an AoE mit.

That's how new tanks see it (minus the boss positioning because many tanks never learned that), because they don't use any of their mitigations or other abilities, but once they learn to use their full kit and protect the party, it is a very fulfilling role and you see how versatile abilities such as Blackest Night, Intervention, Nascent Flash or Reprisal are.

Let's consult SE for their definitions.
  • Tank: These classes and jobs utilize various defensive and enmity-gaining abilities to keep the enemy's attention, preventing other party members from taking damage.
  • Healer: These classes and jobs utilize various curative abilities to restore the HP of party members and remove status ailments.
  • DPS: These classes and jobs utilize various offensive abilities to dispatch enemies as quickly as possible.
So even by SE's definition, defensive abilities to prevent party members taking damage are indeed one of the responsibilities of a tank. It only mentions that healers should heal and use Esuna and that DPS should use offensive abilities to attack; it does not mention that healers or DPS should use defensive abilities at all.
