This would be a good idea because, it would provide a needed social zone. This zone would use a portal from major cities. You could customize the house as you see fit (what the house is made out of, the paint on the walls, furniture, ect). There could even be games that you can buy threw vendor or black lion trading post. Also there could be achevments that give you iteams you can put on desplay in youre house (you have 1,000 kills in WvWvW so you get a banner to hang on youre wall). Well thats my two cents in, so tell me what you all think.
