Personal opinion only, I don't think there's much point.
You can port to your house from anywhere, and port to anyone in your guilds and friends list.
I agree, yet disagree...i think it would be worth it to have the wayshire in the house just to save the time to port where you want and not having to find someone in a place you want to go or just porting to a person and then porting to where you want to go and then also eliminate the animation of porting to someone....yes, its a minor convience but considering most things in the store aren't worth beans at least something like this would be of use...could even do different styles...i don't know, maybe its just me but it seems like a no brainer.
Porting is so cheap that I don’t think there’s much demand although sure it would be cool. They still want to incentivize you to travel through towns though. MMO’s always pick something mildly useful (mailboxes) are a popular choice and keep them out of housing to make sure players don’t lose all incentive to travel through towns on occasion between questing.
I don't always drink Skooma, but when I do I go to the Southwall Corner Club. May you walk on warm sands my friends.
