I disagree with the OP. Just because you don’t want to be sociable and do more in a MMORPG than run around slaughtering monsters/other players the entire time your logged into the game, doesn’t mean everyone shares your opinion.
Having a “home” on an RPG game makes perfect since. In fact, it’s one of the features of Aion that keeps me going back there to play when I’m bored on GW2. Aion set up their housing system to give lots of perks and incentives to players. You go home when its time to log out and because your character has “rested” you receive repose(an XP bonus) when you log back on to play. Aion has their housing system set up in a way which makes it fun to visit friends and guildmates and this adds to the social aspect of the game. Guild members and friends can visit each others homes and do simple daily tasks like watering guestblooms and in return they receive items they can exchange for things that are useful in the game. Coins used for ranked gear, enchantment stones to add to armor, furniture, wallpaper, etc. It’s a very rewarding system with a minimum amount of effort. And the task of setting up your home is optional. Many people participate and enjoy it while others don’t participate at all.
I don’t feel adding housing would useless and if done correctly, it certainly wouldn’t take away anything from the social aspect of GW2. In fact, you may be surprised how much closer something like a housing option would make the community. Variety in a game is important. People need more things to do than just running through dungeons and going from point A to point B killing monsters/other players all day long. This can become very boring.
