Outside of very shallow, childish, apparently still stuck in that high school group mentality beliefs that being in a group entitles you to better stuff, there's only one reason to be against OPTIONAL matchmaking. The dev time it takes to implement it. And that has to be minimal, there's already matchmaking on heroic strikes. I can picture Luke Smith sitting in a meeting where someone brings up Nightfall matchmaking and him just going "nope, it's end game." And the guy retorting "but it's easier than the heroic strikes." And then Luke putting his hands over his ears going "lalalalallalalala can't hear you!" I think Nightfall is [i]supposed[/i] to be endgame, but the hot water they got in by forcing DLC purchases to use it has turned it into a level 270 joke. But really, even prestige isn't incredibly hard. Ran dozens going for the specific loot without mics no problem. The raid, I'm more reserved on this having matchmaking. I can see getting stuck with that green 6th guy every single time and the guy with the five below gaming mic. Trials, if you want to get stomped why do the sweats care? Just more easy early matches for them.
