With Desynthesis on it's way with the next patch

[Nicobo]

I'm pretty sure it'll work like the "request melds" feature. So that you won't be entirely giving them ownership to the rare items.
So it's a good idea for SE to go about it like this as desynth isn't the main attraction for crafting. It's sorta like frontlines as it is it's own kind of thing.
So boo hoo for all you crafters who want to do everything yourself lol
Just make friends and create a network of who's doing what and problemmmmmm solved.

Then you may want to raise the least popular skill as it can make yourself more helpful ^^;
