343 should have a forging contest. The objective? Make a balanced map, for a matchmaking playlist. And after finished, they could be uploaded to file share, and judged by 343 dev’s themselves. And the winning map could be added into matchmaking! This could bring some more variety to matchmaking!
That would be interesting.
In the meantime, though, you can submit maps for consideration via this thread. It isn’t as exciting as a contest can be, but it’s still useful.
