With the expansion, we'll be able to venture into the Caverns of Time
, where we'll be able to travel through time and visit crucial moments of Azeroth's history. We're tasked with safeguarding the past, but... why? Will Alliance players really be enthusiastic about aiding in Thrall's escape from Durnholde Keep? Do any of us want to return to the past only to idly watch as Medivh opens the Dark Portal, for example? It seems Nozdormu really needs to work on his advertising pitch...
And if we have the power to travel to the past, why not use it to fix things? Tired of farming to create a Scepter of the Shifting Sands? Why not just go back and prevent
Fandral Staghelm from smashing it in the first place - or better yet, take it from him? So we can travel into the past - but why don't we change it?
