It was a cute idea if this game had any sort of mythic + system that allowed you you to get past 600 gear score but no one is doing content right now .
At level 60 there is nothing to do but grind gear score and crafting ( which is just time or buy gold and max it out lol) expeditions are dead content.
The reason end game expeditions are dead is because people are hoarding orbs they are super hard to craft have a daily limit of 1 and 3 per week . You can’t sell them etc.
My suggestion make orbs work in a mythic + system allowing people to get past 600 gear score and then leave regular dungeons spammable ! Because the dungeons are really fun but no one wants to use their orbs till they are max watermark .
