I agree that the set up for unbound crafting is less than ideal (he said, understating). But we're a week ish from live and they've shown no sign of being willing to change the actual design one iota, they haven't responded to any of the queries about whether small/medium/large Eberron Dragonshards will change in terms of drop rate to assist people in getting crafters to make them gear. About the only thing they've 'changed' and to be honest I read it as 'we hadn't decided what to do about this anyway' its been the non-scaling effects (e.g. UWA) which they seem to have somewhat arbitrarily scattered across the tiers.
Unbound crafting is something that I think they simply don't want you to do anymore, they just didn't want to come out and say it. So now we can add cannith crafting to the list of things people do alone for only their own benefit without any involvement or interaction with other players.
I've more or less given up. It'll be what it'll be.
