I feel that it's too late to fix it now, given all of the interdependencies between items, quests, etc.

But really I'd have to ask... "What were they thinking!?"

When Treasures came out, did they really have to duplicate the whole stinkin' fish list, to add new fish that were essentially the same, but named different? Such as Cobalt Jellyfish and Denzisansi (or however you spell that). Both fish are used for the exact same thing, but yet they felt we needed yet ANOTHER fish, lol.

The OP has a point, but sadly what she's proposing cannot be easily done. They've dug themselves yet another hole they can't get back out of, and man this game just inundates you with junk left and right that heavy use of wikis are all-but required because you don't know what any of the tens of thousands of unique items are Actually used for.

And you know, there's still items that are not on the wiki that I still don't know if I need.
