More Races and NPC's

What do you guys think would be a good addition to Halo 5 in relation to NPC’s or alien/human races?
I was thinking that it would be cool to bring back ODST’s and Brutes back into Warzone and maybe even adding the option in Forge to spawn NPC’s.

When I read the thread title I thought you were going to say Halo 5 needs a race gametype. But now that I’m here, I’ll just say I miss the Brutes

Yeah races will be cool too!
