This has been an annoyance of mine as well. The goldsmith leve 2 x 2 Eyes in Limsa requires guild support, but the guild is in Ul'dah. So after I get the leve I go get the materials from the NPC and then do the actual crafting later when I am in Ul'dah. Of course, then I have to remember to deliver it next time I am in Limsa (before picking up new leves), and this would be quite inconvenient if I actually could find 8 rank appropriate crafting leves to fill my journal with each reset.

There are plenty of recipes that do not require guild support, so why not just use those for crafting leves in cities without the guild?
