Might be why the next new story installment is taking so long. It cannot just be another chapter it has to wrap things up into a conclusion of a storyline. As much as I want new content, I hope they take their time and give Dark Reign a really excellent farewell event.
Are you sure they're going to release another chapter in Dark Reign?
I was thinking about trying to do something like this with the essentials listed, to try to pattern an order of some sorts.
