To promote specialization within industries, something that can limit the feeling of being burned out by having to keep every single one of your vast grouping of different industries all at the same level of competitive status, I'd like there to be a mechanic introduced that allows a village to declare itself as specializing in a certain sort of industry, essentially a smaller version of a realm buff applicable to villages that gives certain advantages and buff toward types of industry present in hafen, i.e. farming, mining, perhaps even sub-industries such as specifically being tailored to brewing, cheesemaking, steel-forging, etc.
I feel that if properly implemented this could encourage work between villages, either in global trading by allowing smaller groups to be hyper competitive in one industry that they can use in conjunction with a major market to bring up their other industries through trade or in local groups by having several villages within a few thingwalls of each other that each excel in a specific area of the game and thereby encouraging these people to reach out and try to enact commerce and group play among one another - thereby bridging the gap in experiences between the two predominate styles of play in this game, those being massive faction play or hermiting
