This was basically the only other alternative to crafting and potential for weight gate. Think about it. If crafting really did "remove the satisfaction of obtaining a random weapon", which is factually wrong for several reasons, especially when you consider weight gate being proven to be a thing for YEARS before Renegades, then the only ways to satisfy players is to make every gun have: * Comparable value in stats and perks, exotics included with few to no exceptions. So all 720 smgs for example would get their AA increased to match Barrow Dyad, or Ace of Spades getting another 20-40 stability to match what you'll see on probably every 140 hand cannon in pvp after perks like Perpetual Motion as well as another 5-10 AA. * There needs to be good chances of getting the rolls you want for the weapon you want * And there needs to be no "bad" combinations with each other or perks that conflict with the weapon type. So Threat Detector on a sniper for example shouldn't drop ever, and combinations like To The Pain+Harmony also shouldn't drop. And weapons with Kill Clip can't get perks that can reload the weapon based on hits/ kills such as Rewind Rounds or Subsistence. The tier system addresses at least one of these to better replace crafting. It also saves vault space because one weapon could have multiple perfect combinations like a Giver's Blessing with Rewind, Moving Target, and Demolitionist in the left column and Kinetic Tremors, Zen Moment, and Adagio or Adrenaline Junkie in the right. It sounds to me like there are almost no negatives to this tier system except that it partially invalidates older weapons that will become absolute stat monsters if this game lasts long enough to reprise them. I can just imagine my best Rose for example (void Elemental Capacitor) having 85 range and 94 stability. Or what I consider my 2 best rolls for Redrix's Estoc, the tier system would revert most if not all the nerfs except the ADS damage fall off scalar and AA.
