Many things killed it off. I’d add external databases and addons.

It is not that I hate external databases and addons. They are great and help a ton. But they also did remove the “exploration” part of the game. If you know exactly where to go and addon also plans out the optimal route +if you do not know what to do, external database will tell you in details - this kills exploration and player interactions on top of dungeon-finder and auction damage.
