Classic New to wow, why do players want the Invincible mount?

I read up on the back story a little bit and I really like the lore.But I just don’t get the appeal of this mount outside of the lore. It looks like any other horse and it doesn’t even have any special effects on it.What am I missing? People have been farming this for years! via /r/wow https://ift.tt/3jX3CRz
