I have to wonder how the system would look if armors/garments/shoes adopted the same system that weapons have.
For example, all weapons drop with options, and have different option tables depending on the level of the monster dropping them. On top of that, weapons dropping from fever fields have a unique option table (that is ostensibly better than normal field option tables).
Why not do the same thing for armors? They all drop with options, across the entire game, with different option tables depending on the level of the monster that drops them. But those that drop in Fever Fields have a different, stronger option table to roll on. Effectively, you're trading the power of the options for variety in equipment - maybe a Formal Suit won't have as good options as an Orc Dungeon Coat, but you can still lean into it for the Formal Suit's own special features (extremely low weight, in this case).
I'm not sure how much you'd want to scale the non-fever field enchants down, or if it would be better to instead scale the fever field enchants up a bit, but I feel like it could go a long way to making a huge amount of currently useless gear at least worth picking up and checking.
