Everything we show you before launch is subject to change.

Nope. Sorry!

/u/Mark_GGG any chance of an engineering blog post on how the map layouts/packs are generated? =P

Not from me, I don't understand most of that stuff.

Correct

Marshes can be affected by 5 Sextants.

Mausoleum, Marshes, Dungeon, Pillars of Arun and Courtyard would be the five for that one.

Just a note, making sure that every single Map can be affected by 5 (or more) Sextants is something that I ensure each time the Atlas changes.
