I like the idea how new MMOs now are taking the player run theory. Politics, environment, trading npcs all covered by real people. However, what about mobs. What if the only way to level up in the world is to kill each other. So once you get out of newbie island, everywhere is open PVP because the whole game is truly player run.

So the best grouping system for this would be the Shadowbane system, where guilds are categorized by favor of certain professions, fields of mastery, races, or world views. Then there are also Nations, and alliances. This forces you to join up and group up as soon as you leave newbie island, so you're not caught wandering out alone to get beat up (obviously if you played shadowbane, you'd know there were many classes who could wander out alone because they'd hide their presence on the map, ie scouts).
Because the game is player run, resources are important to keep up. So those crafting grievers left alone will get punished by their people for messing up their land.

However, unlike other MMOs, who have such crafting system that effects the world: in an open PVP world, you would get nothing done. So we'd take in RTS' idea of having moving stations a guild/nation can fund and place together and put near resource zones. The whole guild can work together to unlock features that allow automatic gathering, so crafters can spend more time on making products than getting them, and etc. Pay mind that Cities are no-PVP zones, until raid hours, but main guild cities are always PVP zones (for enemy nations and guilds).

Obviously, it would be annoying that all you can kill to level up is other people. So it'd be creating, destroying, and capturing points that'd gives you the most exp. This would up the strategic and tactic aspects of the game. Objects you build outside your cities will give you bonuses - and every map has areas where you can build certain things to give more bonuses to your nation or guild. So of course these will be the zones small group will hunt and fight at.

Wouldn't that sound great?
What would you guys add to make a game like that amazing?
