In a way, Shadowbringers was the first expansion that was about saving a world. Endwalkers saves the universe.

So I'm fully expecting things to scale down massively in terms of plot. Perhaps Y'shtola finds a way to traverse worlds and we go there in 7.0 for a fresh start.

I would even welcome a 7.0 built as a completely new universe where we all start at level 1 again with a fresh inventory. It will be the cost of traversing to a new world. But we will be able to teleport back to the old world any time and have our old levels and items back.

New players will be able to start with veterans at level 1 together, instead of having to crawl through 90 levels of story.

The only problem with this is that they won't be able to sell level skips...
