I recently got an idea that can might improve Halo gameplay. We always wanted Pelicans or Phantoms on multiplayer and I think 343 should do it since a lot of people wants to make awesome machinima. Also, I was thinking about adding a new big space battle gametype for halo 5, wich could be like Star Wars Battlefront 2 spaces battles. No one ever made that since Star Wars Battlefront 2. A Covenant CCS cruiser vs a Halcyon Class Cruiser in space. Vehicles: Coves-Space Banshee, Phantom and Seraph fighters. UNSC:-Shortsword, Longsword and Pelican.
We could also add a ground to space battles map(a massive sandbox). Objectives: Destroy enemy ship by capturing ground-to-space canons, by shooting the other ship or by entering the enemy ship and destroying generators or stuff like that.
