Well, what is there really to do other than the hearts? Gathering materials is something I do while questing, i'm certainly not interested in running around aimlessly hoping to find resource nodes, or running all over the map to explore every nook and cranny while I have already spent hours roaming the exact same scenery.
If anything, they just need to add
more hearts.
I solved the issue by going to Hoelbrak and questing there, but I didn't really enjoy having to do that. I'd much rather progress through the areas smoothly so I can experience all-new content on my Norn or Charr character.
