I had multiple tells about it and so I had to go see for myself - you know how when you had a cat vanity pet out and you typed /sit it would go and sit on your lap?
Well now in druid travel form it sits on your back!
I tried it at first and it wasn't working but I realised you have to target the pet and then type /sit. It doesn't work when I just sit down with a hotkey either.
And yes, Ancient, that pet is named after you!
