So we get Artifacts to defeat a few demons, close a portal and beat Kil'jaeden (again).
Next up we have bigger threats Void Lords? Queen Azshara and Nzoth? The Corrupted titan inside of Azeroth?
We wont be ending Sargeras in Legion without major fuck ups on Blizzards part (he's simply too huge and powerful for us his right leg would be a end raid boss itself)
So what will we be wielding after legion that is better then an legendary artifact weapon?!?! :s
