Long time since I've made one of these posts. The last one was suggesting they buff Bangalore's ultimate which did happen. Console (Xbox) player for context when needed

1. Buff the Hemlok. Slight reduction to vertical spread and increasing the burst follow-up speed to pre-nerf levels. The Hemlok struggles to compete with automatics at short range due to flinching making follow-up shots inaccurate.
2. Remove the .30-30. The pick rate is abysmal and can't improve without making it overpowered. Replacement would be the Nightshade, a DMR version of the Hemlok with a longer barrel and barrel shroud and a shorter mag (Doesn't exist but this is the suggestion). Existing Legendary and Epic skins would be retooled for the new gun.
3. Remove Shatter Caps. Integrate it into the Bocek and remove it from the loot pool. Doesn't really improve the Bocek but I can see the appeal. Precedent is Precision Choke and Selectfire Receiver.
4. Remove the Charge Rifle. Out of place and has the same damage profile as the Longbow. while being far more difficult to use. Replacement would be the Thunderbolt, a railgun using the same firing system as the EMBAR from Gears of War 4 and Gears 5 where the user aims, pulls the trigger, then the gun charges and they have a small window of time to fire after. Higher damage than the Sentinel but far slower fire rate. (Doesn't exist but this is the suggestion). Existing Legendary and Epic skins would be retooled for the new gun.
5. Custom reticles. Pick your color and the shapes will just be available to pick from and they will be made available as packs like in Call of Duty.
6. Pistol nerf: P2020 and RE45 would have increased damage falloff at range. 9mm and .45ACP aren't exactly known for their long-range performance
7. New gun suggestion: Heavy pistol. Desert Eagle style gun. Higher Damage than the P2020 but lower than the Wingman. Compatible with Skullpiercer Rifling but not Hammerpoint Rounds.
8. New gun suggestion: Crossbow. Coil Spring style rather than classic limb spring. Higher damage with lower fire rate than the Bocek but fixed fire Rate. Alternatively, an arrow gun that uses light ammo and arrows
9. Hop-up suggestion for Thunderbolt and Nightshade: Plasmacaster. Improves damage vs shields, adds punch through for energy barrier shields (Rampart, Dome Shield, Gibby Arm Shield), reduces the effectiveness of helmets. Requires Energy Ammo
10. Remove white helmets and white knockdown shields from the loot pool. Unnecessary since everyone has them and you don't need to swap them in combat.
11. Barrel stuffing nerf. Knockdown shields will reflect 100% of damage dealt back to the shooter if the barrel is in contact with or through the shield.
12. Could try this as an event or a new legend's passive ability but DBNO status. Allows the player to shoot pistols while down.
