I have the same issue with my (still relatively short) Midlander. I often can't see the nametags on larger bosses to target them easily - as PS4, at least, has an issue with not 'seeing' things if their name is off the screen.

Famfrit in Ridorana Lighthouse was terrible with the Tsunami attack, because I can't easily see which way the ewer is pointing unless I tilt the camera up. It took me a while to even realise where to look.

I tried adjusting the camera height but it messed terribly with where I thought my character was standing for ground AoEs.

Being able to zoom out further so I can see the whole arena clearly would be great.
