With the coming of legion, we're getting various artifacts that heroes through the ages have wielded. From the Ashbringer that took down the Lich King, the Scythe of Elune that created the Worgen and contains the blessings of a demigod and god alike (Goldrinn and Elune), all the way to lost artifacts such as the staves of Tirisfal Guardians past. It's now common knowledge that we're getting a majority of the most powerful weapons and artifacts on Azeroth, and it has been stated by Blizzard that artifacts will not carry over into the following expansion.
This left many people wondering what will happen, with some worried that we'll replace the Scepter of Sargeras with a green quest reward at level 112. However, I'm curious as to theories of what we'll get that are a little more interesting.
My theory (and probably shared by others) is that we'll have to go off-world for our next tier of weaponry. We're already doing this for a few of our artifacts, so it would make sense that the only thing more powerful then the artifacts of azeroth would be the artifacts of far more advanced worlds. OR we uncover parts of Azeroth that haven't been touched since the titans themselves were here. In essence, the next expac would have to involve titans, off world shenanigans, or old gods in order for us to surpass the power of our artifacts.
Anyone else have viable theories of where we go from the end of Legion?
