Ok, combined arms was a failure. Bungie removed it after only a few months in Year 1. The vehicles were too easy to destroy, made the driver to easy to snipe, and didn't respawn quick enough. The maps had to small of an area for driving and to many indoor areas where vehicles could be avoided altogether. The vehicle combat was so glaringly disappointing that I was baffled that Bungie included vehicle combat in the original release of Destiny. And yet I still want vehicle combat in Destiny.
