It appears that Bungie listened to feedback during the console beta that said skill-based matchmaking should be toned down or removed in the casual Quickplay playlist. While skill-based matchmaking isn’t going away entirely in Quickplay, it is being reduced. To further emphasize the more casual experience, Bungie is also extending the score cap for a match and adjusting the Mercy Rule trigger:
In the Competitive playlist, skill will remain a driving force with a mix of connection-based matchmaking to help reduce latency during the match. This seems to be what fans will traditionally recognize as classic Destiny matchmaking:
These changes will be present for the PC beta, which goes live with early access (for those who pre-ordered the game) on August 28. Bungie will likely be watching this beta, just as it did the console beta, to judge how the new matchmaking settings are functioning out in the wild.
Hardcore fans of Destiny are pretty happy with the changes announced to matchmaking, considering that the topic in Destiny 1 was an ongoing point of contention between developer and fans. As always, the PC beta and (even more so) the full game will be the true test for how the new matchmaking feels.
Destiny 2 releases September 6, 2017 for PS4 and Xbox One, and October 24 for PC.
