Confirmed with Disciple of the Hand lead

Currently there are no plans to add any new low/mid level crafting recipes.
We designed FFXIV so that gear obtained from dungeons is more effective than crafted items.

For their first class, players can gain equipment from the main quests so we don't think they should face any problems. But we believe there are other chances to use low-level gear, such as creating materia or equipping them when leveling a second class.
