This was mentioned in the Devblog as a possibility and I see some interesting pros and cons here. I like that this gives a sort of dynamic class system to the game. You could have 1 person that crafts a lot of armors, another that does weapons, numerous mixed up variations of that in between. There is some incentive here for co-operation.
On the other hand if the restriction is to restrictive it could excessively hinder solo-play.
On the whole I think the benefits to gameplay are greater than the losses, but I think there may be ways of addressing this issue for solo-players.
Alot remains unknown about this idea, what do you guys think?
