I mainly play desktop, so I don't know how this affects VR, but when I turn my FOV up (in my case, from 60 to 90), even with the nameplates at the highest scale I can set, nameplates still look rather small and are hard to read (and even harder with the open beta nameplates). The nameplate scale should either have more range for size scaling, or the size of the nameplates should remain the same across different FOV values.
