Balance the DPS of the weapons and class abilities/equipment. You’ve chosen to create a class based shooter which is fine, but then the DPS/abilities/equipment with associated classes needs to be appropriate to drive team strategy with individual class selection. Light=fast/lower DPS at range, Med=average speed/DPS, Heavy=slow/high DPS. Example: the light class shotgun does not do enough DPS at close range to make it a viable weapon comparative to the assault rifle. The damage drop off at close range is disproportionate and drives players to select other weapons purely on DPS (which I’m sure you have more player data on to have a deeper insight). Similarly, the heavy classes weapons do not do enough damage at range to effectively make them “tanks” and defensive strategy players. Essentially, you have the illusion of classes, but the DPS will dictate weapon choice, and the benefit of the class ability/equipment will eventually lead to a dominant class/weapon combo that you want to avoid to encourage deep/customizable combinations. You don’t want to mimic the trope of the plasma pistol/battle rifle combo trap that Halo 2 fell prey to.
