Originality? 4/5-5/5
Dont rate something 5/5 just because it has recon in it....
Sounds like the Farcry2 map editor from ubisoft, if Halo added these changes it would be well worth the 800ms, even 1600, however, that would present many problems.
People wouldn't be able to enter your forge games without the pack ( having dlc that isn't available ), and it would be a huge change in their game, probably requiring a maintenance of some sort.
If bungie did it, would be great, but highly, highly unlikeable.
