I have mixed feelings on the super crafter template. I have a few crafters. One has GM carpentry, smithing, tailoring, bowcraft, tinkering, arms lore, and enough magic/music for pentagrams/instruments. It is nice to keep crafting contained to this character, and use my other slots for macers, fencers, tamers, treasure hunters, mages, necromancers, spellweavers, samurais, ninjas, etc. etc. etc.
One crafter is Legendary Smith, Legendary Tailor, GM Arms Lore, GM Mining, and other skills that will probably go away with a soulstone when the new skill comes in. The second crafter is focused on making armor and weapons. There should be an advantage to specialization (a tank mage shouldn't be as good a warrior as a pure warrior or as good a mage as a pure mage).
I'm most likely going to need to GM this skill at least two times (several accounts problem) depending on which skills need it (3 times if inscription can use it). Either way, there is going to be some soulstone activity to make room for it. Even if most people had two crafters instead of the one, they would always be full since there is always a craft skill people forget (just when I think I have them all, I figure out another).
