If you guys check out this link to the new game that is an RTSFPS hybrid I’m sure you will love this idea. I will bring back halo wars fans as well as fill that void for the spartan ops and firefight seeks to as halos secondary multiplayer mode.

Imagine UNSC versus Covenant with different playable classes like grunts, ODSTs, Hunters, Spartans, Elites, and any other halo cameo you can think of.
IMO this would probably be a problem on the xbox 360 but since Halo 5 is supposed to launch on the next gen microsoft console it seems feasible.
