Ok, so after Taken king and during rise of Iron bungie implemented the matchmaking system we have now. It sort of worked than. Destiny 1 also had a smaller weapon pool to choose from for crucible. In D1 we didn’t have bows, grenade launchers, smgs, or linear fusions (technically). The issue with the sbmm that bungie used to use is that it de-prioritized connection quality, meaning people with all sorts of connections, crappy or perfect would be put in a game together, creating mountains of lag for everyone. What that system did prioritize, however, was your K/D of the previous game. This meant if you had a bad game with a K/D less than 1, you would be put with other folks with a K/D less than 1, meaning you could pubstomp easily, just throw a game every now and again and you’d be fine. This also meant that if you had a decent K/D for your region/country/continent, it could (and often would) pair you with guys outside of your region/country/continent, creating even more lag. This was pre taken king matchmaking, and people cheered when it was removed. Bungie tried only once to add it into D2, during CoO, and it went horribly, as lag spiked. People got upset again and it was removed. Bungie’s next (and current) solution plays into the ranks, at least in competitive. The way glory works, you gain rank for winning and lose rank for losing. Therefore raising your rank and keeping it requires skill, logical right? So bungie implemented sbmm based on that into competitive, and haven’t seen comp complain about it too much. Quickplay is for finding a quick match as seamlessly as possible, sbmm would only slow the process, as it can take a while to match “properly.” Do you get what I’m saying?
