Thank you for posting that - I totally missed this interview! And props to Staten. The things he described seem to be paying HUGE dividends. I am already seeing clips of people loading up a Razerback with five or 6 Marines to take into battle, and I love that type of stuff.
This is 100% the stuff that has been completely missing from Halo4/Halo5.
That sense of being in the midst of a big intergalactic battle with humans fighting covenants and flood fighting everyone.
Based on the footage I've seen/heard it seems like they've really found a way to bring this feeling back.
