Hi. I just wanted to bring attention to a bugged perk interaction that negatively impacts weapons that can roll with both rampage and explosive payload in separate columns. (TLDR version. Explosive payload drops the damage of a weapon that also has rampage. Its a pretty bad interaction. at 1 stack of rampage, a weapon should hit for 10%, but at x1 with explosive rounds, it only hits for 4%. This issue persists as you increase rampage stacks, making rampage an even worse pick) Explosive payload + a damage perk has long been a solid perk combo choice for endgame primary weapons. For example, explosive payload + one for all or desperate measures on midnight coup, explosive payload + frenzy on fatebringer or doom of chelchis, etc. This is because the damage boosting perks add damage on top of the explosive bonus damage, allowing for some pretty solid single target damage on primaries. I think this is a great thing to have in the game, allowing primaries to have some single target usage at the sacrifice of ad clear perks such as firefly/dragonfly or volt shot/incandescent/destabilizing. The reason this works so well is that the damage perk is added ON TOP of the explosive payload damage bonus. However, there is an exception. Rampage is a perk that stacks up to 3 times, allowing for 10% at x1, 21% at x2, and 33% at x3. Its honestly not a bad perk. Sure, in end game it falls behind due to failure to maintain up time on such a short cool down, but in normal mode raids or strikes/onslaught/seasonal content, rampage is a solid perk. So, rampage and explosive payload should work well to just have a nice damage increasing weapon, right? Well, if you look at explosive payload + rampage together, at x3, the damage bonus should be 33% + %10-15% = 43%-48% right? Wrong. Actually, the damage at x3 goes DOWN from 33% to 31%, meaning you end up having less damage than a simple rampage midnight coup. Even at just x1, what should be 10% is actually a whopping small value of 4%. I have not confirmed this, but apparently arsenic bite with explosive head and rampage also has the same issue. What I do know though is that explosive payload + rampage is causing the weapon to lose damage when it really should be gaining damage. Something is wrong here. I am sure this is known by plenty of players already. Sadly, I am just finding this out after enhancing a midnight coup with this very roll, and also crafting + enhancing the rereleased ancient gospel from Garden. But it makes no sense why rampage is the only damage perk to have this sort of interaction where the gun actively hits for less damage while having 2 damage increasing perks. This, by default, makes rampage almost immediately a bad perk on hand cannons and scout rifles (and maybe on arsenic bite too?) because many players genuinely prefer the feeling of explosive rounds. Instead, in a sandbox where rampage already struggles to keep up on certain weapon types, rampage will be automatically overlooked in favor of other damage perks. What is the cause of this? Well, I personally believe that this is a 2 part issue. For one, rampage is a year 1 perk, and so is explosive payload. Weapons probably could not roll with these two perks together, so the issue was never highlighted. The second, and probably more scientific answer, has to do with rampage and how it interacts with explosive payloads damage splitting. When you put these two parts together, it would make sense that an older damage perk like rampage likely doesn't interact with the damage splitting properly, but newer damage perks likely do interact properly. But I don't actually no the true answer. Either way, I really hope this gets looked at, because even though rampage and explosive payload together sounds kinda boring, I personally like it, and I am seeing content creators always recommend this perk combo on ancient gospel without understanding that the perk combo is actually detrimental to the weapons performance. And I don't blame them. The two perks should be working together pretty well. Anyways, thanks for reading all the way through. If a bungie employee does see this, please consider looking into it. It isn't a game breaking issue at all. But it is a sad perk interaction considering every other damage perk works with explosive payload. Thanks.
