S17 Sandbox Clarifications

"Flinch resistance directly scales the angle your aim moves by when you take damage, so if you have 60% flinch resistance and you would normally be flinched 10 degrees, you would now be flinched 4 degrees."
Scalar means multiplier

No Distractions: 0.65x
Suros Synergy: 0.8x
1x Unflinching Armor Mod: 0.75x
2x Unflinching Armor Mod: 0.7x (i.e., this value is used instead of multiplying two unflinching mod values together)
Rally Barricade: 0.5x
10 Resilience: 0.9x
100 Stability on an Auto Rifle: 0.75x
100 Stability on a Sniper Rifle: 0.9x

Airbourne can not go below 0
Accuracy perks like Opening Shot will feel less impactful in the air
When airborne you basically have separate aim assist cones for the crit vs the body
When airborne, magnetism and friction are halfed, and then the aim assist airborne penalty is added

Lightweight pulse buff affects the BXR!!!
Retraced path is getting Trace buff
Slugs are effected by the damage fall off changes and the airborne accuracy changes
All SMGs have improved damage falloff
14 zoom is not the default for all SMGs, just the ones mentioned
Full Auto setting not coming till S19, so use the mod still
Sidearms were niche enough that Bungie left them alone
Summoner going away so quickly to make room for a second new weapon
Bungie hint's here about Trace and MG champion mods

Vex treated as auto rifle for airborne effectiveness
Wavesplitter isn't changing it's function
Riskrunner and Osteo zoom staying at 13
Lumina is affected by the damage reduction
Le Monarque is poison now, but NOT a weapon of sorrow
Arby and Lorentz are being handled separately and Bungie is watching them going forward
Devil's Ruin and Fighting Lion not a concern with the Special ammo reductions
Eyes of Tomorrow buff is 1.3x against bosses and champions

In S17, you can get gold borders by having "an enhanced intrinsic perk and two enhanced trait perks"
Crafted exotics will need a catalyst
