The game is starting to show a lot of information in-game that was previously hidden such as monster ranks, monster aggression and soon hate levels in battle. All of it is useful information and following that pattern, I think the ranks of crafting items should be displayed in-game as well. I'm talking about the hidden ranks of crafted items which determine how difficult a synthesis will be for your current rank and how many skill points and experience points you will yield from attempting the synthesis.

It shouldn't hurt the game in any way to be able to see this information. It would also be nice to see the recommended ranks of sub crafts needed for items that do require them. I don't think it should effect the display of items normally but to see the item crafting rank in the menu before starting the synthesis would be fine. Somewhere between the information of shards required and recommended treatises would be a good place to display this information.

Just something simple like...
Celeste-blue Cotton Cloth x3
Recommended Training:
Weaving Training
Dyeing Training
Recommended Rank:
Rank 19 Weaver
Required Shards:
Earth Shards x7
Water Shards x3

It is a bit silly and troublesome seeing how much information I actually need to learn outside of the game to craft properly or efficiently in 14. If you're going to show me the rank of the dodo I am about to fight, I would like to see what rank the item I am about to craft is as well.
