Considering it is already coded for Strikes and Weekly Heroics, adding it to Nightfalls at a minimum should be a piece of cake if their developers can code at all.

The developer has stated explicitly why Nightfalls are not match made, and Raids are a no brainier

When I was saying that they could easily implement matchmaking in Nightfalls at a minimum, why did you even bring up Raids? And quit trying to change the subject from how easy it would be to implement the already coded matchmaking for Nightfalls to whether Bungle was stupid to say they don't want people to use matchmaking on endgame activities. Different point entirely. (Troll losing argument tries to change direction of discussion.)

To be fair, when you see matchmaking rants, it normally is about the raids. I haven't seen people calling for nightfall mm in a while
