It's part of the MCU 10th anniversary celebration, so the regular order is not observed at the moment. It seems the essential character is a fourstar and the fivestar it feeds.
...so I am totally expecting Shuri and Okoye to be Essentials after Webbed Wonder. If it can be a new and revamped Fight for Wakanda awarding a new fourstar Thanos (he is in the last node on the Astral Plane sub after all), the better.
