Safe Havens (essentially up to 16v16 Infection meets Firefight meets Dominion, with the exception that all "enemies" are playable. No AI-controlled Flood)...
Depending on how this would be implemented, I think it could be pretty awesome. Maybe have their be a few different types of flood classes with unique weapons/"armor" abilities, supported by hordes of combat forms/infection forms. Something kind of like a Left 4 dead/firefight/invasion hybrid in Halo would make my day. Perhaps in Halo 5, 343?
Also, if this were to be on xbox 720, perhaps with the additional processing power we could have the ability to have hordes of A.I. teammates on each side: survivor side having marines, ODSTs and Elites (of course being infectable by the flood if not protected) and the requisite swarms of flood supporting the "special infected" players on the flood team. They would have to find a way to drastically improve the netcode over what we saw with Reach's firefight though.
