Both of those games were masterpieces of the SRPG genre. Awakening is a good game in it's own way, but it brought the series in a totally different direction. The series needs to go back to its GBA roots or else it will just be another Disgaea.
I prefer some elements of the new, some of the old. I'd like to see an FE that goes map-to-map, but much longer, with time and options for catching up units, and as much if not more customization than Awakening.
