I think new alexendria was a pretty boring level. Bungie really dropped the ball on that one, they could have made it so you start out with you falcon and go to the hospital to rescue civilians, then go meat up with noble team somewhere. Then, you split up, 3 members go to take care of one building then you an someone else go somewhere to do something. Like, you and Carter(you didn't have any missions that were focused on Noble 6 +carter) go to club errera to take out the hunters and save the troopers(who are creepy IMO, it seems like they stare at me all the time). Then you and carter could call for a pelican to transport the troopers and pick up the rest of noble team, when over the radio you hear Emile, Kat, and Jun talking and then Kat dies, and you don't witness it, but you hear it. So when the pelican comes, you pilot it(properly pilot it, not like a Halo 3 hornet with no guns like the pelican was to fly in reach) and you picked up Jun and Emile, then Jun detected a radiation spike, you you had to get to the ONI building and get underground before you got glassed over and the city got glasses in sections.
