I hate when people make a fuss about the time-travel in this expansion and how "it doesn't make sense".

Yet when Interstellar does the exact same thing, everyone loses their fucking minds, and thinks it's the greatest movie of all time.

AND I DIDN'T EVEN LIKE INTERSTELLAR!

Do yourself a favor, watch the following movies:
-Interstellar
-Deja Vu
-Harry Potter and the Prisoner of Azkaban (yes, really)

Then you'll be able to answer this question:

The fact that the time travel loop raises questions . (like how did hydaelyn know to be a primal at level 50 if you never went back into the past till level 90).
