Eloquently written and great points. The new guy kicks ass.
In the case of Halsey, I'd assume she's on the burner for now until the Spartans are needed to (ultimately) take on the escalation of the Didact threat.
Guaranteed plot point in Halo 5 or 6. Spartan II's will save Halsey from the UNSC.
Roland just comes across as a bland Cortana replacement. His personality is pretty inconsistent through Halo 4 and I agree with the other forum members that have said his cocky moments were annoying. I remember during a legendary play-through that was particularly grindy, I quit the campaign for a break because Roland's comments were troll level.
