I completely agree with your analysis. Especially since this is not only 343's first attempt at a Halo game, it's their first game that they've ever put out completely on their own! And I think that, while there are a lot of vehicles in the multiplayer matches, but I feel like this can be a good thing in the long run. It promotes the people who like to play support classes more (i.e. using overcharged plasma pistols, plasma grenates, etc.) to go out there and turn the tide of the match. That being said, there are still plenty of people for the marksmen in the game to pick off on the ground!
