JUST MY OPINION! If you have a different opinion, feel free to tell me below.
I think the story telling through the journals around the map is lame and not really that fun to do.
I think you at rare have 2 different routes you can take.
1: Add more stuff to the story quests. Wich is kinda a waste because it is time limited for some reason and players who missed the event won't be able to finish it.
2: Skip the story with the journals and add the story through dialogs. Then you can focus more on the actual features.
