They need to rethink how they do story in 7.0 +

You can see it as you like,that's fine. A filler is part of a story that if you take out will have no effect on the story.

We don't always see how relevant something is when it's first introduced, though. Case in point, Alisaie's whole story with Ga Bu. That seemed like just side filler to add some character depth, but ended up being incredibly important. And they do this throughout the MSQ.
