As a lala, any time I lock target that is even slightly larger than me, my camera view is forced to an upward position, and I'm unable to zoom out or see anything around me. If they could make it so your view is locked so you can't swivel side to side but up to down, it would fix this issue. I was unable to see the cone of attack on the ground fighting old six-arms, and got repetitively trounced.
Had the same problem in xi, and really wish they'd do something about this.
