Placeable npcs in forge is something I've wanted since halo 3. It would be fun to be able to make mini campaign missions and also just make maps more alive. I would like to see a better campaign for halo 5 as I didn't enjoy halo 4s. I think they got over eager and overkilled the whole forerunner thing. The levels were not very diverse. The promethiens I thought looked like a robot dog, a RC helicopter, and a over powered big triangle and not at all original halo material.
