Earlier this month, Bungie released Destiny 2's newest dungeon, Vesper's Host. It's a pretty good time—a fun reprisal of the some of the mechanics introduced in the Deep Stone Crypt raid, and with some unique boss encounters to boot. Good job all around, surely there won't be some major week-long drama off the back of it.

Reader, there has been major week-long drama off the back of it.

Nestled in the dungeon's loot table is a grenade launcher, VS Chill Inhibitor. It can roll with new perk Envious Arsenal, which automatically reloads the magazine when you deal damage with your other weapons. And it can pair with Bait and Switch, a perk that gives a 30% damage bonus when you deal damage with your other weapons. It's a perfect combination—absurdly desirable in terms of boss damage phases. People immediately started to farm for it—repeating the dungeon's first encounter over and over for a chance to get that specific roll.

One problem: people just weren't getting that perk combo to drop.

You can see [[link]] this , which uses the API to scrape weapon perk stats from players' inventories. Envious Arsenal is the second most popular perk in the third column. Bait and Switch is the most popular perk in the fourth column. The combination of Envious Arsenal and Bait and Switch? It doesn't even make the top eight of most popular combos.

This led to a growing conspiracy theory, "Weightgate," that Bungie was weighting weapon perks—deliberately tipping the scales to ensure the most desirable rolls are much rarer, thus prompting players to keep coming back to the slot machine of weapon RNG for one more go. Some players attempted to , using data from a set of players who collectively farmed the encounter thousands of times. The problem was none of this was conclusive. Players who did already have the Envious Arsenal/Bait and Switch combo are going to stop farming for it—and so any sample of people who have thousands of clears by definition is only going to include players who don't have that roll.

On the other hand, a felt pretty definitive: "There is no perk weighting active for any legendary weapon perks in Destiny 2." It did little to quell the growing dissatisfaction, though—the data, flawed as it may be, felt right based on people's own experiences.

And as it turns out, the doubters were probably right. Streamer Vendetta proposed a new "brand of copium"—the , suggesting that perks that were listed closer to each in the API had a greater chance of dropping together. Amazingly, based on further drop analysis from Twitter user Newo, it seems to be true.

This analysis shows a clear pattern of drop chances based on a perk's proximity in the game's code, and it seemingly applies to more than just the new dungeon's weapons.

Light.gg has that displays graphs for all of the game's weapons, and the evidence—particularly for those from recent episodes—seems pretty clear. There are a lot [[link]] of graphs showing the telltale diagonal gradient that suggests a perk's proximity is having an effect.

Enough so that Bungie has responded again, reaffirming that "there is no intentional perk weighting on weapons within our content setup," but confirming that the studio is now investigating "a potential issue within our code for how RNG perks are generated".

The reason that this has been such a major talking point among the Destiny 2 community should be clear: in any game with RNG rolls, it's important that players can have confidence in the fairness of the system. God knows, anyone who's played enough of any loot-driven game will have horror stories about bad strings of luck—RNG that feels like some invisible hand is preventing you from what you want. But, in a perverse way, that's also part of the fun. In a [[link]] perfectly fair system, the next run could be the one—the big payoff is just around the corner. That context is very different if there is actually some force preventing you from getting what you want.

Ultimately, though, I think the Light.gg admins have a pretty good take on this.

Sure, plenty in the playerbase are ready to believe that Bungie would weight perks—the community's most enduring cynical take is that the studio will do anything it can to increase player engagement metrics. But also Destiny 2's API is a genuinely exhaustive thing, and gives the community the exact tools that were needed to 'catch' whatever current issue is affecting weapon perks. It would be wild to intentionally try to fudge the numbers while so much raw data is easily available.

It is, though, funny that this drama has surfaced in the same release that Bungie began work to deprioritise the weapon crafting system. It's not clear exactly how extensive weapon crafting will be going forward, but none of this season's new weapons are craftable as yet—. For now, at least, it's probably best not to spend hundreds of runs farming for a god roll VS Chill Inhibitor. At least until Bungie's investigation is done.

Update: And just like that, Bungie's investigation is done. Just days after stating that "there is no perk weighting active for any legendary weapon perks in Destiny 2," and hours after this story was published, the studio has confirmed that there is indeed something hinky going on.

"After investigation, we can confirm an issue has been found in our code where some random perk combinations are harder to earn per legendary weapon perk set," Bungie wrote on . "In some cases, desirable perk combinations are a bit easier to earn as well. While we inspected our content and confirmed each perk is weighted equally, an issue in perk pool RNG is the culprit here. Our team has quickly identified a potential solution to the issue, and we are rapidly working to validate the fix."

Bungie said that a date for the hotfix will be announced as soon as possible. The studio is also aware that players want a more detailed explanation of how this happened, but said that for now it's focused on getting a fix finished and deployed: "After, we'll be sitting down with the team to discuss all the nitty-gritty details."
