Michael, We are in the same boat. ESRI has been in the mindset for a while of single task maps. We have been in the need of a map that could be used as a kitchen sink to see all kinds of data with more then just a single workflow. There have been some promising options and templates out there, but when Web Appbuilder came along it was heaven sent. Very little coding to get all the rich features we needed. We too are replacing a catch-all map that was built using ArcIMS by people before I got it. It has been running by a thread and WAB now replaces all the functionality and then provides a ton more. Our users are loving the new map. Thanks ESRI and GeoNet crew for making me look like a rock star.
