Noticed around late April that gunsmith bounties were severely restricted in what can rotate through. Started tracking it every day since then just to confirm suspicions. Currently only the following weapon types exist in the bounty pool: Trace, Fusion Rifle, Glaives, Rocket Launcher, Linear Fusion, Machine Gun Weapons Missing: Auto Rifle, Bow, Special & Heavy Grenade Launchers, Hand Cannon, Pulse Rifle, Scout Rifle, Shotgun, Sidearm, Submachine Gun, Sword, Elements: Arc, Void, Kinetic Elements Missing: Solar, Strand, Stasis
