I am not sure if you are aware of the home portal stone (https://wiki.guildwars2.com/wiki/Home_Portal_Stone), or if you are requesting a change to that which will allow you to choose which home instance to port into. If you do not have the portal stone, I highly recommend getting one. It will port you to the home instance in the city of the race you are playing and then back to the world where you started before traveling. I'd like the home portal stone to allow you to choose which home instance you enter. I'd also like Suns' Refuge to be a home instance (nodes and all) so I can do desert harvester there.
