Not quite, you needed to have a Druid specifically in your group to get it, as it was part of a Druid specific chain. It's only since Cata that you can get one without the use of a Druid.
Yeah but anyone could still use it, it wasn't druid exclusive you just needed druid help to acquire it.
The fact that you specifically needed a Druid weighs it in favour of it have being primarily a Druid perk which they could take advantage of IMO
Ya I said that in post #6 But it was introduced way back in TBC right? Also while it's one of the best looking ground mounts IMO why have a giant bird king mount and not have it fly
