"Gun Curve" philosophy is broken and flawed TLDR at the end
There was mention few patches back about not buffing The p2020 and Mos because you wanted to game to have a "curve" so the weapons get better over the course of the match when upgrading parts.
Just wondering if you played Apex before saying this? Because i want to know where the is curve when you get a P2020 and your opponent has a Peacekeeper arguable the best weapon in the game? Sure the purple make the peacekeeper better but barley you can wreck with a normal peacekeeper. When the damage output is so vastly different how is that curve of weapons? To me that so random luck vs curve.
With this said you should either buff the those weapons to make them more in line with like every other weapon.
Or
I think you lower all the weapons time to kill to be about the same in the early game and then make the upgrades change the time kill speed. So that maybe lowering damage of some weapons or reducing rate of fire or something.
This would make the game have the weapons curve that you were talking about and less of the RNG luck.
*Side note* you should do somthing about the peacekeeper and wingman that fact that 90% of the player uses these weapons or looks for these weapons say something about the balance of them.
TLDR
Should normalize weapons time to kill for early game and make the upgrades increase the time to kill to add the "weapon Curve"
Or increase the P2020 and other lower weapons damage to bring them in line with other weapons early game.
Side note Wing and Peacekeeper need some changes considering 90% of the player base looks for and uses the weapons.
