You just discounted the argument about the time it takes to obtain a perfect roll noting your experience and then admitted that you didn't go for a perfect roll. If you're not targeting only the perfect roll your experience means nothing Okay rolls aren't good enough, and for many weapons every single perk matters. Heavy Grenade Launchers for PvE are a key example. Blast Radius actually reduces your impact damage with Spike Grenades so right off the rip you need Hard Launch if you want a Spike-nade roll and of course the traits are essential, then the Masterwork must be anything other than Blast Radius of the roll is a dud. That's one of many examples where anything short of perfect is no good at all RNG in Destiny is simply too punishing we need RNG forgiveness for regular weapons
