Because you wouldn't grind as hard for that perfect roll.

Because bungle like taking a great idea then making it so bad (or irrelevant) that everyone just gives up.

I suppose because collections is about being able to re acquire items with rolls you've already had and not items with rolls you haven't had before. They probably could log the code for each individual roll of an item that you have had before but I imagine opening collection's would take considerably longer. I do think that it should be possible to re roll one aspect of an item already in your inventory. Like being able to re roll the masterwork or one perk for a cost of 10 cores per roll. Once a masterwork or perk is rolled only that particular perk or masterwork can be re rolled and nothing else on that item.

As much as I would like it god rolls would be all that matters, kind of the other side of the spectrum too. I'd say we're in middle ground but rng is still a sob, and the only thing you can pull out is pinnacle weapons. If they're going to do it it'll be at a greater cost, although I don't why curated can't be pulled.

I would assume because it's not difficult to amass a large number of the materials required, and a lot of players already have thousands of some (all?) resources that it would result in many obtaining every single roll they want in a short space of time. And that then results in no point playing the game which is something Bungie do not want. Must. Grind. Moar.

I wanna know why we cant either.
