I have a suggestion for Halo: Reach or Halo 4 matchmaking. I and many others would love to see race in matchmaking, on community maps, that would make Halo extremely fun again.
Other things that would be awesome too are bringing back Rocket Race. I loved playing Rocket Race, however now the alternative is RHR, which is fun, but sometimes I just want a mongoose and I don’t want to play a load of multi-team games to get it.
Adding in Battle Tracks (like rocket race but on linear tracks and with different weapons) would be amazing too.
It would be brilliant if more fun community mini-games and gametypes made it into action-sack or something.
If the awesome people at 343i could consider some of these suggestions, I and I know loads of other people would have loads more fun on Halo.
