I genuinely want to love this DLC: the story is so good and ties really well to the main game, the soundtrack is still a banger and the gameplay is just different enough from the main game to make it original... But my god, forcing the player to do sidequests to progress the main story is just miserable: Xenoblade's sidequest system just doesn't work, and forcing the player to do side content absolutely kills the pacing, especially when it's just before the climax...
It's still a great experience, but the pacing alone made it way worse than it could have been.
