to add to the list bring back the small adjustment thing from halo reach and have an actual blood gulch map, and not to be "that guy" but really... forge island... come on 343, you can do better.
ive always wanted to have a firefight forge so you can make a warzone point where you want the enemy to spawn point where your odst's spawn and finally the spartain spawn. this would be awsome because you could remake your favorite halo fight.
