Remember when the Glamour system was new, and we had a TON of different Glamour Prisms? Grade 1 through 5 for each craft! Eventually Square Enix decided to remove all of those and go with universal Glamour Prisms that work for everything. A very clean solution that benefits everyone.

Now let's bring our attention to the dye system. There's over 100 different items used to dye our gear and not a lot of reason for them to exist.
Almost all of these dyes are relatively worthless -- available at NPCs for cheap or on the market for similar amounts. Very few have any sort of value.

It would be nice if we could combine a lot of the common dyes into single items, for example all of the non-special Blue dyes could just be a single "Blue Dye" item.
For the special dyes, they could either remain the same or be combined in smaller amounts depending on rarity.

Regardless of the solution, I think it's odd that we are getting an update to the dye system in Dawntrail but are keeping this heavily aged part of the system.
