So I have returned to play some WoW and decided to level a hunter. Well, to my surprise I discovered that the pet’s fetch ability was missing from the spellbook and then from the Dragonflight pre-patch skill trees. WHY?
Why do you always remove the fun things from the game?
Please bring it back!
Fetch comes from the Legion Class Hall as a tome spell that you can learn optionally, you can also get Play Dead for pets so they can Feign Death too.
All of this they just moved where its acquired
Mine still works fine…
Do I have to redo the Class Hall to get it?
For every new hunter yes, its not account wide. That means going to Legion Dalaran, grabbing at least 1 artifact weapon, and doing the whole chain to get it up and running.
You should be able to learn it from this gentleman, too:
Please Disregard my complaint! I was not aware of the new changes. Thank you guys for answering so fast and helping me out. 
I almost had a heart attack… don’t do this to me!
I am sorry 
I had one. Couldn’t find any info online.
