I was in Hew's Bane when I decided to focus a quest asking me to go to Stros M'kay. Since I did not have the wayshrine for Stros M'kay I have decided to follow the quest marker. This is the route it took me:
Hew's Bane >
Woodheart >
Markbruk >
Eldern Root >
Haven >
Skywatch >
Vulkhel Guard >
Daggerfall >
Stros M'kai
...all the while I have already had the Daggerfall wayshrine available to me. If only I knew that the ship to Stros M'kay leaves from Daggerfall I could have avoided wasting all this time.
Expected behavior: The quest marker should take wayshrines into account and lead me to the nearest shrine, and then to the nearest discovered to my target. So in my case:
Hew's Bane >
Daggerfall >
Stros M'kai
