It is not that it is unwanted. I don’t like coordinates as I find them confusing. That is okay if someone goes, I need this type of tree trunks from this planet and you can find them at this location, or this color of rocks, sand, soil is found here.
But a shop? Coordinates would have me going Nuts! I want to know what town, city, settlement it is close to and what other portals are close by so I can find it.
Can remember some time back when I was given the coordinates to a settlement that had a shop. Problem was, the portal that I had used for it closed down, then I had to travel a long distance to find the shop. And low and behold, there was another shop close by it that was a well known one and had a portal to it that I saw at several locations. I could have gone to any portal area and have been there in a few seconds, not swimming, climbing cliffs, dodging critters, climbing out of holes I had fallen into (I was around level 25 then) and going this place wasn’t worth all that hassle.
Your suggestion to add it is a good one, I just never think of it. For me, portals are the best way to find it, and portals that will lead to it from several locations, not just go through this one portal. That one can close down. I don’t have a portal to my shop. It is at Nova Golda Market, and there are portals to it in various locations so it is easy to find.
Lots of players, not all but many, are now putting their shops in markets or malls as it makes it easier for players to go to one area and look at different shops. And remembering the name of one mall that can have several portals that lead you to it just seems easier than trying to remember the coordinates to it. Which I am always losing where I put the paper that has those wrote down on. sigh
