I had 3 major complaints:
1) too many echoes, most were worthless. If nothing else needed a quick select for the key echoes.
2) zelda needed to be able to attack directly. The sword meter was expired too quickly. Watching echoes battle, especially with awful AI, was boring.
3) Dungeons were meh. LA's dungeons were much better.
Game is solid, I enjoyed it. 7/10.
