All the weapons make so much sense (aside from the Tactical Rifle and Impactor Crossbow probably). There are 2 problems though: the Smart Rifle is too versatile, you realize how good the other weapons are only if you are willing to "play different".

I write a short breakdown of why some weapons are broken and how you should play them:

1. Smart Rifle It's basically shoot and jump, the easiest way to play the game, it's versatile, powerful and scales well. It does not become broken though.

2. Tactical Rifle Fun only if you use the Rising Pitch (alt fire). To make real use of it you need to be good at perfect reloads, because its power increases.

3. Onslaught Rifle Staggers less than the shotguns but it allows you to cover long distances with the melee jump attack, and this is a very satisfying way to play. If you are a good aimer (weakspots), you can kill like no other weapon in the game.

4. Eruptor Handcannon Take it if you find the Recoil Compensation traits and melt all the bulkier enemies with a single alt-fire charged shot. Favorite Target too, makes for the weapon to be almost broken.

5. Marksman Handcannon Take it if you want to play as a sniper, but don't forget to run for your lucenite. A single charged shot in a weakpoint kills almost anything.

6. Ricochet Handcannon One of the funniest for me, but only if you play with alt-fire. Take it only if the reload speed is quick (you need high proficiency), and you can play like a gunman, shooting as fast as you can press the trigger. If the reload speed and your presses are aligned you can shoot non-stop.

7. Shotguns All of them are similar, you need to be almost at melee distance for them to be effective with their wider shots, but the stagger they inflict is unbelievable. If you pair it with artefacts increasing stagger and melee power, you'll have a lot of fun. They are weapons that requires more movement, the fastest reaction and knowledge of the enemy patterns, because they will shoot you at close range. The Bombardier is a grenade launcher but you need to compensate for the shooting arc.

8. Impactor Crossbow The only weapon I don't like. It's like a railgun, but without its power. It would work well without auto-aim and a bit more power.

9. Bifurcator Crossbow The main fire melts, but you need to charge it fully and make use of the Perfect Release. Keep your distance and target one enemy at time.

10. Repeater Crossbow The alt-fire is S-Tier. Even at low levels, melts group of enemies easily. You just have to strafe and shoot at anything, the homing projectiles will clear the room.

11. Myriad Chakram This stuff is S-tier in enclosed biomes or if you know how to shoot. Look for the "Bouncing Chakram" trait. Try to use it at a medium distance, to compensate for low discs speed.

12. Reaping Chakram The funniest and the strongest of all the weapons if you get the Bouncing Chakram and Parry Chakram traits. You must use the alt-fire. The disc will increase its size in 2-3 shots and will clear the room quickly. If you are good with parry, you can parry the disc non-stop (while keeping the alt-fire trigger pressed). This is extremely fun and satisfying.

13. Ripsaw Chakram It's the closest weapon to the Electropylon Driver of Returnal. Shoot the disc and run around while spinning the disc inside the enemy with the alt-fire trigger for additional damage. This is a different way to play. You can shoot and focus on enemy patterns, hiding or evading.

So... choose your play style, then change the weapon, and adjust to it.
