Developer Bungie has already detailed a number of PvP and matchmaking changes coming to the Crucible in Shadowkeep, Destiny 2's fall expansion. But in the developer's weekly "This Week at Bungie" blog post, new details were revealed specifically about how Crucible scoring and streaks will be changing in Year 3.
First off, scoring streaks in Destiny 2 will no longer fully reset upon a loss but will instead the streak will be reduced a certain amount of points depending on the playlist. For Valor, which is earned in non-competitive modes, basically just for playing Crucible, a loss will reduce a winning streak by one point. This also applies for Infamy streaks in Gambit. When playing in a playlist where Glory is earned (the competitive ranking system), a loss will reduce the streak by two. The new system should give players a little more leeway for failure without wiping out their streak after just one loss.
Losing Glory is still very much a thing; however, Bungie is also making each Glory ranking tier below Fabled a hard floor that players cannot fall back under once they have crossed the threshold to a new rank. While they can lose Glory within each tier, each new tier is like a checkpoint for players that they cannot drop below. Players can still lose Glory and drop below ranks in the higher tiers of Fabled Mythic, and Legend. This should make it easier to climb up to Fabled but then up the ante for competitive in the higher tiers of the ranking system.
In addition to that, skill rating is now being attached to Glory ranks starting from Guardian I to Legend. Depending on how good players are currently and the data the game already has available to it, Destiny 2 will determine what tier a player should be in based on skill. Everyone starts at zero as always, but until players reach their assigned rank, they will earn more Glory points on a win and lose fewer points on a loss. Once they reach the rank the game has determined they belong in, Glory points for wins and losses will normalize.
As mentioned previously, the Competitive playlist is going away in Year 3, replaced by a 3v3 Survival playlist including a playlist for solo players. This is a pretty significant change to the Crucible coming in Year 3, and it will be interesting to see how this affects the climb up the ranking system and earning any existing and future pinnacle weapons attached to Glory ranks.
Destiny 2: Shadowkeep releases October 1, 2019 for PC, PS4, and Xbox One, with a Stadia version also in development.
