The Champions' Ballad's biggest accomplishment is what the base game struggled with the most - the story. It's nice to have context about the Champions and their relationships with Link. Outside of the story, The Champions' Ballad struggles with rehashed content (shrines, divine beasts) which isn't something I was hoping to see from a DLC for a very long game. The post game content, puzzles, and bosses however thrive as a result of being DLC, and I believe they provide some of the highest highs in the "Wild" duo-logy.
