I'm a huge fan of Spartan Ops, but Halo 4's host detection is making the entire thing very unpleasant. Two of my friends and myself both run on wired connections, live within the town, and have generally fast internet. Our third friend lives out of town, has a wireless connection, and can barely classify his internet as 21st century acceptable. Oddly enough, almost every game, our friend who lives in the country manages to obtain host, thus, giving everyone else extreme amounts of lag plus severe latency.
Then again, even during the odd time when one of my friends from within the town manages to obtain host, we still suffer from latency, just less severe.
Get this figured out asap, 343.
