That’s what the difficulty mode selection is for. If you want an easy One-Shot experience just play on the easier modes. Overpowered over tuned weapons just create assholes in the higher difficulties kicking people out of games for not taking “the correct” load out.
Those of us with a little more time or a little more skill or a little more both enjoy the harder difficulties actually being… Difficult. Imagine that, the correct place to give people the ability to have a Nerf mode is in the difficulty slider which thankfully the developers have done!
Instead of complaining about weapon balance just turn down the difficulty and enjoy your easy experience
