Let's use enhancement cores to customize weapons. Tjay makes making them hard to come by and expensive make sense. For 5 cores I can increase range, I can spend another 5 and do it again or use it on handling. I could make amy weapon I want perfect over time. Still considering weapon class limits. So max range, max handling etc is different for different archetypes but in any case I can make that weapon incredible. Edit: maybe for 20 cores I can increase the power of celestial nighthawk. Things like that.
