I would REALLY hope that isn't the case. Or rather, that if it is the case, that it's a negative.
The idea that one person COULD outfit an entire guild AND this not be a negative or tedious process ALSO implies that one person could outfit an entire smaller node. Now, that's SORT of good, but wouldn't one do this over multiple days?
Isn't it BETTER to have 'daily crafting' to do? That sounds a lot more like the problem being on either supply or demand side, not 'crafter'.
I mean, in my experience the crafting was happening when the supply supported it. I could log into the game one day and the GL would say "we've gotten all the resources you need to craft 20 sets of armor, go do it". Now L2 had the step by step system, so I'd start from crafting t1 into t2 and finish at "press the button 20 times to craft 20 instances of this particular gear piece". And then repeated that for each of 5 pieces in a set.
It was done through one crafter because it'd be a trusted person, it'd be a person with recipes already registered (you needed them registered to be able to craft the items) and at the lvl that supported the craft itself (depending on the server, this was also a long process).
And in that context, I look at AoC's system and see that only a few people would be able to master a particular direction. That mastering would require a ton of crafting, so it's beneficial to start crafting all the things the guild would need on that one person to boost him asap. And artisan reputation seems to matter too, so on top of your guild's crafting you might want to help out people in your node or maybe even in the whole vassal system.
And I look at that and see potentially thousands of crafts. And that's just within one "patch" of the game. Any expansions would bring more stuff. And any decaying (which will obviously happen) would most likely demand more crafts.
Now obviously you can split this all up across multiple days or even weeks, but, again, in my experience that shit don't work like that. If my guild needs the best possible gear for their next raid/siege/pvp encounter - I'm gonna craft it asap. And if the guild is working correctly, supply will be ready for me when I need it.
