Just some ideas for DLC.  
Forge World came with 5 maps out of the box.  
Asylum (Sanctuary from H2), Pinnacle (Acension from H2),  Hemmorrhage (Blood Gulch from H1), Paradiso and The Cage. 
I think the DLC should be a Forge World map. One being an Urban environment, another one with a sandy environment and one with a snowy environment. 
Urban Environment would have remakes of Turf , Headlong (Best ever BTB map) and Terminal. 
Sandy Should have remakes of Relic, Burial Mounds and an underground part that has a remake of Water Works. 
and the snowy should remake Sidewinder, Containment and Lockout.  
 
What do you think the DLC Should have?

Yes. God yes. This is my biggest issue with Forge world is that I want more to build on. The Halo 1 forest island environment is great, but I'd love to be able to play with more variation.

I want a DLC that removes Race/Rally from Matchmaking.

How about ...
What the fuck ever happened to Jun. Bungie needs to pop out an episode to plug up that huge fucking plot hole.
 
Not to mention the fact that Master Chief John 117 isn't around kicking all kinds of Covenant ass while he's down there.

I would like to see some campaign DLC, maybe seeing whats happening on other parts of the planet during the invasion. Some classic maps are always nice to see though 'Last resort' is my favourite.

New armor and helmets would be nice.

Race/Rally is awesome. You clearly do not enjoy fun.

I would really like an option that would allow me to reach through my TV and punch anyone that votes for Infection. You have no idea how much I would pay for this.
