Not that I’m against randomly popping into existence still being a thing in video games or anything…but c’mon, we’re living in the future! Let the Spartans feel like ODST. lol…probably not possible, especially since so many (especially Corvette) are indoors, but it was just a random thought I figured I’d share…
The whole FF scenario needs a bit more epicness IMO. It would be nice if you actually land with a falcon and have to clear some kind of a landing zone first, before you can walk around on the map.
The first wave should be already on the map and from far away your team is coming in, and you/all players have to kill the enemies from the gunner seats 
And after that, you can try to “take over” the battlefield the normal way.
