Parties vs. Parties in Matchmaking?

I play MLG playlist a lot and I was wondering if they were going to match parties with other parties more often even with the given ranks.

I noticed in Reach most of the time I would join solo I would get a To4 or a To3 on the other team, where when I joined as a To4 we would constantly play randoms.

Also will 343i enforce no party chat in game like other games have been doing?

Has 343i looked into this and tried to make MM more specific to the joining team’s list as well as the ranks?

I’m guessing nothing has been announced about this or nobody has any comment. Does anyone want this or dislike this idea?
