With the '4 disciplines' and the 'see-saw' mechanism of being able to learn skills (i.e: you cannot max out all your levels or skills on a single character)... combined with the 'degrading weapon resiliance' that are all mentioned on the official website...
It looks like you will have to create mules. One to be your blacksmith to repair your armor, one to be your gardner/miner to get the mats to repair your armour, and one that you can actually go out adventuring with. (2 or more if you want to fully explore all of the 'job' possibilities.
This is just speculation on the new information, but I really hope that this ISN'T what FFXIV comes down to.
I can't imagine many players wanting to specialize in blacksmithing only, and logging in each day on their main character just to repair people's gear and get gil. (again this is said in reference to the 'see-saw skill balance' that has been mentioned by the developers).
This would be throwing away the good things about FFXI, and keeping the bad.
(IE: no 'single character system' and promoting 'mules'.)
