Memories of Reach REQ pack

So I just got back into playing Halo again not too long ago, and apparently I completely forgot about there being a Memories of Reach REQ pack. For some reason I didn’t get the pack. Why is this pack not available anymore and why didn’t anyone from 343 specify how long this pack was going to be out for until it was taken down???

The pack was pretty well advertised when it came out. It was stated that it would be available for a limited time, which, as with similar packs in the past, tends to be about 1 week from the release of the pack. All of the packs are really just a quick way for players who have unlocked everything / have a lot of points to spend, to get all the latest items from an update. If you haven’t unlocked everything, you’re generally better completing your lower levels first.
