I myself use teleports quite often simply because it saves me more time. I have seen and will see certain places and maps more than enough so I dont even want to see more of it by constantly having to fly through it all.

But I have an ingame friend that only teleports when there is a hunt or when he goes to city with the free teleport. It seemingly is no problem for him and he just dislikes teleporting but when we do treasure maps and stuff like that we have to wait for him which in turn of course wastes our time.
