i don't think content for DoH / DoL would be good , crafting is something that should be a little boring but help to have better gear and other things .
I think it works well in others mmo , you see some silver while doing a quest , you mine it and when you have done all the quests in the camp you craft some items .
In 1.0 you can't do this because you need to change your gear entirely every time you want to gather something , i hope they add a system that auto change your stuff when you want to mine ( and remove that slow , boring mini games )
if they add quest for DoH / DoL it will become boring , what people want in FF 14 is kill big bad monsters and epicness not have quest such like , go gather me some woods ...
Or maybe if they add some farm creation and stuff it could be funny ...
