The fact that this time around, they recorded multiple scripts for your "mission control"; Ghost, Ikora, Zavala, Eris, and especially Cayde. Who is better than Cayde? Earlier I was running the Shield Bros. again for the Nth time when I got a different set of speeches from Cayde. Instead of being humorous, he started talking about how many scouts he'd lost to the Bond Brothers, and his tone was deadly serious. When the mission was over, he congratulated us on ending a pair of war criminals. It was like a different Cayde had come on the mike. I love how different facets of the Vanguards' personalities are coming out, just in these strike soundtracks. And when Ikora says she wishes we could study the Vex... *weary sigh* That never ends well.
