Bungie like to make decisions based on assumptions rather than tests. They assume average players will be overrun by better players, they assume we don't really know what we need or want, they assume we don't mind being matched with players 10'000 miles away and I assume that this is bad science! They just need to test higher priority CBMM on a 6v6 playlist such as the new individual entry playlist where teams cannot dominate. But it won't happen. They will continue to use assumptions and numbers and ignore actual player feedback. Assume, never check, it's a good motto for Bungie Devs.
