It's genius... It's so stupid and simple, your "weapon rolls" can be memorized in collections much like Exotics are memorized, and you can reaquire the rolls you had much like reaquire exotics. If you select a weapon it opens a new tab with all the rolls you aquired or "saved". Your weapons come back in your inventory with 1100 power and no masterwork. Meaning you don't need to have all your god rolls in your active inventory, infact, in collections tab you could choose to delete the bad rolls just like items in vault to remove clutter. For devs and programmers who believe this would introduce absolute chaos in their existing database you are wrong, every roll combination is pulled from shared pool that way if you have 125000 players with same weapon roll, it's a single weapon not 125000 instances of that weapon, I think this is one of the reason why their game is not optimized well. Yeah only for weapon rolls, armour rolls would cause problems because you could "clone" your god rolls :D It's genius...
