When you encounter the instance when you fight Lakshmi in the Ala Mhigan Throne Room, just use the controller. It includes the pressing R3 to use Deflect on the Aether spheres, which is nearly impossible to do when many of them spawn at once. Using the touchpad to do this is incredibly cumbersome. I ended up failing the instance a couple of times, until I used the controller (and it was still a challenge to complete). So keep this in mind before you encounter this
