Destiny matchmaking is going back the way god intended, at least for the moment.
Bungie has confirmed that it will be rolling back the changes it made in December after a negative reaction from users. It was designed to match players based on their skill level, not necessarily a bad thing. The issue was that while taking skill level into account, the servers didn't also consider the lag between the matches and the result has been slowdown and uneven connections for many players.
The new Iron Banner event will reverse those changes, making the quality of the connection an important part of the matchmaking process. At the same time, Bungie will also be trying to make sure that players of similar skill levels are paired up, so it's going to be a balancing match to make sure that people are able to comfortably play and also won't get crucified by folks who are several levels above them.
Bungie also said that they would be more open about their plans and changes in the future, with this matchmaking issue arising without any communication from the developers. Users are now calling for a detailed breakdown of the content they can expect in 2016, and we're hoping for official word on that soon.
