I think this story expansion was a gigantic step from Stormblood, Heavensward, and Realm Reborn. It had really good story atmosphere, music, and included/unlockable dungeons, trials, and raids. If the other story expansions bored you and you had to grind through it to unlock stuff, Shadowbringers is going to be enjoyable for you.

The collab raids with the Nier/Drakengard series is also amazing.
