>It's called "Trader."As flippant as that might sound, it's more or less true.
Crafting, in part, was designed to give something useful and entertaining to the lore focused guilds. To create a crafting guild would sort of be akin to creating a "weapons" guild. Not only is it too focused with little room to expand, it gives a giant middle finger to the other guilds who have had that (at least in theory) as a major focus to their guild.
But honestly, with work, any guild can craft anything. You will have to give up leveling and learning non-crafting skills to some extent, but that's no different than in a hypothetical crafting guild.
In short, there's just not enough meat, and I suspect there never will be, to support an exclusively crafty guild. Even Barbarians have to learn out of combat skills (not a lot, but some).
