It has just occured to me that there are north, south, east and west outposts for the Wilderness so why doesn't the Nether have outposts? I think it would be a great idea to have nether outposts so then you can see more of the Nether and maybe get to a nether fortress faster. Anyway tell me what you think about this idea.
But then there is the possability of portal griefing. And most often when you come back from the nether it is laggy and/or nightime. ( This has happend to me before on singleplayer. Came back from nether. Went into house. Tried to close the door but I couldn't cause it was lagging too much! Creeper came in and blew up all my chests and almost killed me.)
