So we could be getting a lore update here regarding the bestest badarse in the cosmos.
HOWEVER: It is also worth noting that scenarios were originally created as a means to replace group quests to make levelling up have more variety. So it is entirely possible Blizzard is adding this just as a way to make Outlands more bearable.
Either way though, what do you think will happen here? I'm betting we'll end up fighting Blood Elven initiates, and maybe some of their Night Elven trainers.
