I've tried lfg loads of times either closed posts people are afk or teams are full or posts arnt taken down or iv made my own an noones joined so don't pretend you know everything when I have tried doing it the so called right way truth its their is literally no reason for mm not to be in game except catering to elitist and basement dwellers
There's no way that has happened EVERY time you used LFG unless you started playing Destiny yesterday. We've all had bad experiences in LFG.
I can think of multiple reasons why mm for everything would be a bad idea:
1. Simply put, it isn't necessary with the tools you have available to you. Bungie can spend their time and resources dealing with ACTUAL game problems. It's also not Bungie's fault if people are too lazy/antisocial to take 15 seconds to make an lfg post.
2. The same people who complain about not having mm would complain about getting bad teammates. If not that, it'll be the queue times or the server connection. It already happens with the activities that currently have mm.
3. The activities you request mm for require communication, coordination, and proper loadouts. Do you really think a matchmade team of blueberries with no mods would last more than 30 seconds in a GM nightfall? And, refer back to point number 2 here, they would then come and flood the forums with their complaining. "Waahhhh, it's too hard!"
4. You know what would happen next? The collective complaining of all the blueberries would likely result in endgame activities being dumbed down, and the challenge and prestige of completing said activities would be less meaningful.
And before you try and call me an "elitist" or a "gatekeeper", check my stats. I'm definitely on the more casual end of the spectrum and I feel this way.
