SOLO/NPC DUNGEONS! This is my number 1 thing that I am excited about. I have not done any current dungeon content in almost a decade because other humans are involved. I have panic attacks. I also get lost really easily. It becomes an accessibility issue for me.
I am beyond excited that we can finally just do dungeons at our pace, see the story, finish quests without upsettting a go-go pug. I can even learn the dungeon increasing my chances of not messing up if I decide to do a more difficult level with others.
I feel like if I had one wish for WoW, that it was granted. I wrote a whole essay on it years ago, and I KNOW that me writing that is not why they did it. I only hope it added to their thoughts on how to make the game more solo/alt friendly and accessible to a wider range of players
