I'd like things that are effectively expansion rewards such as Rajas Ring, Jalzahn's Ring, Moonshade Earring, Desultor Tassets, Suppanomimi, Magnetic Earring, etc. to be updated for level 99.

These aren't normal items. They require that these expansions were purchased using actual money, they eliminate other options when they're chosen, they sometimes provide unique bonuses, they sometimes have unique models, and they might even have sentimental value for people who really like the story-lines.
