Devs just need reconsider housing at all . Just make housing as it is aviable for FC's only , & make personal housing instanced ---> Like it was done long time ago in FFXI (For those who don't know XI had rooms which player able to furnish & invite friends , XI have personal island area where player can gardening/mining/fishing and many other awesome things ) . This solution not perfect but at least it will make less ppl's to /cry about houses , everyone will be able to do w/e they want .
