Yeah me too, as I really believe it would make Land-Play more immersive and interesting as players or even guilds fight over land-influence to gain rewards or Boni, maybe also on a season-basis.
There is actually a similar thing in Stronghold I think I havent touched on in the post: "Glory Race" where different houses/guilds fight for glory and position in a leaderboard by doing quests or by holding Tracts/Regions.
Thats so servers can not be played indefinetly and so there is an overall goal for houses/guilds.
