coop unplayable for non-host

I’ve seen a few posts about this but wanted to make sure everyone was on the same page with this issue. I have been trying to play with my buddy, we play every other game together and don’t have any issues. We’ve ran speed tests, made sure ports are open, etc. But the person who is NOT the host experiences this extreme delay/lag (I’d rather call it delay, it’s a little different than your typical lag) and this makes the campaign unplayable. Especially for anyone who knows what it should feel like.

Help us out, 343! We should’ve already played through the entire campaign and we’ve only completed two missions, just because we sucked it up and wanted to see it. This is extremely frustrating, we are dying to play the rest of the campaign!

Yeah, this is a big let down for those of us who are experiencing this problem. I’ve played co-op campaign on the original Halo countless times and was looking forward to doing it again over Live. Hopefully they can patch it properly.
