1. Most versatile role that can do almost all of the content with least dependency on other players
  2. Is possible to share gear with 4 jobs, so can flex within role easily. Also there is far less difference in gameplay between MT and OT than pure/shield healer.
  3. Often has unique mechanics to deal with
  4. Is easier to play as sturdiness makes it forgivable/allows to greed for uptime/just simpler. Good job when you want to focus on content instead of rotation.
