As a rotating gamemode, maybe, but this is how Destiny 2 Vanilla weapons worked (all one-hit-kill weapons were heavy weapons), and it was disliked by a majority of the community. It would be incredibly unfair to have snipers, but no shotguns or fusion rifles, as that shows clear favoritism to snipers and disadvantages anyone not practiced in sniping. Snipers would also need to be removed to keep the balance. Removing one shot abilities would mean some classes, like Sharpshooter Golden Gun or Top Tree Striker Titan, would lose synergy and be valued far less, so it might be better to limit this mode to no heavy, no single-shot special weapons, and no abilities outside of grenades (including no supers). Supers could work like CoD-style killstreaks, where 10 kills without dying would earn you a super, but that would be it I personally would want to see the following game modes for Crucible: Rift - Just like in D1 Gun Game - Everyone starts the game with a game-generated random legendary sidearm. A kill gives you a sidearm of a different archetype (SUROS rapid-fire first, then aggressive 2 burst for example), and once you pass the two sidearms, you move to SMGs (Pillager followed by Cold Front, for example). This cycles through all primary gun types in the game, followed by special archetypes (only exotics being two of the three Trace Rifles) and ending with power weapons. To win the game, you'd have to get a throwing knife kill (all classes are granted a knife identical to Sharpshooter knife). If you miss or don't get the kill, it takes 10 seconds for it to recharge. This would be 32 total weapons followed by a knife kill, and every time you play it would be different legendary weapons with randomly generated rolls that show up on screen whenever you get a kill. Exotic Gun Game - Same as the above Gun Game, but with exotics. Final kill would come from an Anarchy kill. If weapons change ammo types (Eriana's Vow, Leviathan's Breath), they would still show up in the normal order (i.e. you would get a kill with Le Monarque and move on potentially to Levi's Breath) Infected - Infected all have legendary swords that cannot block but have unlimited ammo to kill Guardians. Guardians defend themselves with a variety of exotic weapons randomly selected by the game, but only one weapon per round (Fighting Lion, Sunshot, Jotunn, Divinity, Devil's Ruin, Cerberus +1, etc...). Infected do not show up on the radar, and every 30 seconds a random Infected is given a Masterworked Worldline Zero as an advantage (disappears on death). 25 kills from a Guardian instantly fills their Super as a "killstreak", but this would be limited to Blade Barrage, Spectral Blades, or Arcstrider for Hunters, Chaos Reach, Nova Warp, or Heat Rises Dawnblade for Warlocks, and Burning Maul, Thundercrash, or Middle Tree Sentinel for Titans Sharpshooter - Everyone gets an exotic w/ unlimited ammo for 30 seconds (no other guns or abilities), getting streaks gives point multipliers and maxes out Guardian stats, new weapon rotated in every 30 seconds) Buckshot Brawl - Sharpshooter with nothing but Shotguns (Legendary and Exotic) Precision Paradise - Sharpshooter with nothing but Snipers and Linear Fusion Rifles (Legendary and Exotic) Voop Violence - Sharpshooter with nothing but Fusion Rifles and Trace Rifles (Legendary and Exotic) Explosive Entertainment - Sharpshooter with nothing but explosive weapons (GLs and Rockets) (Legendary and Exotic) One in the Chamber - Everyone spawns in with a Hand Cannon with one round in the chamber. Headshot multipliers are increased so that a headshot with any Hand Cannon is an instakill (at proper ranges). A bullet or melee kill grants one bullet back to you, and the winner is the one with the highest points earned form kills, assists, and bonuses for staying alive. Hand Cannons used could be Warden's Law, Malfeasance, Duke, Eriana's Vow, etc... Sticks and Stones - Free-for-all with Swords and Fighting Lions. Everyone gets a Throwing Knife like Gun Game, and getting a kill with it removes 3 kills worth of points from your victim

Sounds kinda like D2Year1. We all know how that went.
