We should have an option to stay hidden from the map, so people cant see you on their maps. I know Era has an option like this. Anyway, its annoying because people can add you then know where you are at all times on the map, so it could ruin it if youre trying to secretly group to attack a tower. Also, for tower guilds, if you leave towers everyone can see you on the map, so with this you could slip away sneaky.
