It's time that Blizzard is updating the Archaeology profession. They know it they have to at some point, but haven't found the right direction yet. At least, that is what i believe from several interviews i watched over the past few years.
So i was thinking. When archaeologists starts digging they don't always find artifacts and other items. They sometimes find lost houses, caves, tombs, etc... covered by ground. But digging reveals them. Since The War Within we have Delves. And what if those hidden spaces are in fact Delves that we can find. Wouldn't that be awesome? I mean, i think that Delves can be the answer to fix and extend Archaeology.
Artistic impression of this idea:
How would that work?
First you still need to collect the artifacts. At rare occasion you might find a treasure map. This item allows you to search anywhere, not just inside dig sites. Follow the clues on the map to find the delve entrance. This time the hotter/colder game will be harder as well.
