Give an option to limit the number (or remove entirely) character models on the screen, excluding Party members, when doing events such as F.A.T.E.'s.
When you're doing higher level F.A.T.E.'s, then it's typically very crowded - this means that on the occasions where Bosses/NM's spawn, you very rarely actually get to target them because they seem to have a lower priority than NPC's (Chocobo/Pets) and Players. On some occasions, I can target them and then they vanish again.

Remove the inability to use a mount when you're fighting with your Chocobo.
I have 4 mounts: Legacy Chocobo, Company Chocobo, Coeurl and Goobbue - Why can I not ride my Goobbue or Coeurl when I'm fighting with my Chocobo? My Chocobo can keep up (all mounts run at the same speed), why do I have to burn through Gysahl Greens if I want to use them?
