Haven is Haven. It has the timing and distances intended for Haven.
Other maps from previous games have been scaled to fit the new games they show up in. You can't just port them directly, or else unintended paths and timing show up.
I never mentioned anything about porting directly seeing as how I think remakes bring some better changes to the maps, for example Pitfall. Also, that doesn't address my comment on how other games can have sprint, quick dashes, wall jumps, etc. like Murder Miners, but for some reason Halo can't unless the maps are made larger to accommodate for those things.
And I brought up Haven because Haven is no larger or wider than maps we've seen in previous games without a 3x DMR and sprint. Take Haven out of Halo 4, put it in CE's sandbox, and with some minor adjustments to jump height or whatever else, the map would play extremely well. I don't know man, that whole thing about accommodating maps for sprint doesn't really make sense to me and I have yet to see anyone prove otherwise, especially when many other games pull it off well. Even Titanfall has close quarter spaces that work well, and we all know the movements options in that game. Not saying I want wall clinging in Halo, but obviously small spaces can work with over-the-top mechanics like that.
What's my point? Halo 4 not having 2v2/4v4 arena maps has little to do with sprint being added to the game.
