While you probably have a long term plan for home instances (as currently they are useless) I would like to suggest granting players ability to zone to they’r home instance or home city with reduced charge (or for free 
) You have made great cities that are mostly devoid of player (and home instances that are fully devoid of players) since everyone is using Lion’s Arch. While its nice to see at least one city full of life. Going to the same one every time you want to unload your bags because its the place most efficient to get to is a waste considering how grand other cities are as well.
Something like that would bring some life back to the cities long forgotten, and seeing, for example, more Norn running around Hoelbrak since its their home city would help with immersion.
Just throwing a though out there.
