Anyway I think to "fix" the world of darkness I prefer a world in which many organisation/factions do many things and might come across each other, but are not constantly in the way of the other groups.
Hunter is a good example of how it should be done (although not perfect either). The Loyalists of Thule could be relic hunting for some artefact in the catacombs beneath the city, while the Night Watch is only interested in patrolling the neighbourhood they live in. It shouldn't be a game with one monolithic conflict or divide everything into five cliques, but it should be a living world in which different groups do different things and provide players to multiple things.
It's easier to do in a scifi or fantasy setting though.
