Never knew that. *shakes head* when did that come around?

I can relate when I made my starter pet for some reason I thought that what was showing on screen in the way of traits was what I got to choose from and didn't realize you could change them until like a week or so after. I guess I figured it was my fault for not reading everything about pets before starting. Just tried releasing her and it looks like after you defeat the dungeon of the forsaken you can release them, but I was not able to before this point.
