Suggestion: Add "exception to the rule"-weapons for variety.
As the title suggests, add "exception to the rule"-weapons, weapons that serve a niche with benefits and drawbacks.
For instance, add a M24 sniper rifle, give it no ability to have the sweet spot mechanic, give it 60 damage body shot and always oneshot to head or even better give it 45 damage to body and 2.25x multiplier for headshot without any damage dropoff over range, but no scope glint, and maximum 5 rounds in the magazine with a fairly slow reload.
And add an M110 DMR, headshot multiplier for always one shot headshot, BUT.. give it scope glint, but lower body shot damage.
Also add "outdated" weapons but without customization, like the AK-47 assault rifle, the M16A1, 1950's UZI smg, and RPD lmg. These would be perfect for themed challenges for seasonal challenge rewards, and require minimal effort design-wise, but quickly becoming fun "challenge yourself" weapons that are not necessarily the best options but fun to use and adding a bit of uniqueness to the gameplay-loop.
