I don't know if anyone else really does this, but I use digital maps for everything and just finished the massive battle setup for the HoU scenario. I figured I'd Post this in case anyone else uses maps like I do on a big screen or projector. I filled in characters and waves for everything in the scenario for 5 players. Everything else should run by adjusting the "visible" markers in Photoshop one section or event at a time. I've also included some accents and lighting changes to show the time change in game, and have a layer folder for spell effects as well. All you have to add is some tokens for your players and size them to the grid. Hope this helps someone else save some time.
