I think we need to take this as a fashion. Other than being "useful" like some home instances or guild etc. Being fashion, it would not be mandatory and people who wants to build a home could do that and as a person who works on game developing like myself, I can easily say that this is by no means a big deal. Just some artists working on modeling and skinning.Hence it should not have any impact on game mechanics, it would not need any extensive programming either, only base code like "if/then". And lets be honest, such simple things are not a big work on the Anet staff to work on. And I bet the art department has not a big project on their hands either. So sparing 2 or 3 guys on a "lets make a home" project won't stress their abilities on any part.And as a side note to those who say the devs should concentrate on more important matters like lag etc. this has nothing to do with the art department, so for them to conceptualise some houses and work on them is not a big deal of work which is urgently needed somewhere else. People should realise that there are different departments in game development and that they have different pipelines of work and time schedules. So its not an extra and hard work for the dev team to make this real.
