Didn't read everything, but they're letting us know that's it's their philosophy for no matchmaking for certain areas of the game, and no matter how much some of us want it, they have that right to not include it. Lots of people have been asking for it for nightfall and Vault of Glass since the game came out...they don't want to implement it. I'm fine with that. We don't have say in what goes in their game, only suggestions and requests.
