Oh, really? That's really good to know. I would suggest by the look of that it seems there is netcode data within the map packs which intentionally throttles how much bandwidth the game is allotted... I really want to know what support has to say about that, because it sounds like you just caught a thief red handed... if you catch my innuendo.
Also, the more map packs you have directly affects the number of games and lobbies you can find since the primary search will always look for individuals and parties with the same packs installed... which means it at least initially skips over lobbies of people who don't have any map packs, or might only have say one and never bought another - which immediately limits the number of possible people on the whole server you can connect to and play with at all. This was a problem with Ghosts when by this time last year there were only around 30 thousand people connected at a time. When I had all four map packs I would find myself playing with the same few groups on a day to day basis when it tossed me in a lobby and it was taking anywhere from 40 seconds to 4 minutes to find a lobby at all some nights. When I deleted all but the first map pack (because statistically the bulk of the community will buy at LEAST the first one anyway), boom, instant lobbies every single search. Which means the more map packs you have, the less people matchmaking will bother trying to put you with, it'll just flat skip thousands upon thousands of potential players and lobbies simply because they don't have those map packs, if any at all. It's always kinda been that way, so this isn't new information, it's just necessary to inform anyone new or sorta new to the franchise as a whole.
In either case, it REALLY doesn't pay to buy more than a single map pack anymore... at least half the playerbase on any given console doesn't get the season pass or doesn't buy more than the first one (if they buy any at all), so you're basically crippling yourself in terms of potential players to match with and lobbies to be put into... that's sad.
