At this point I think this is an issue that should be something for the player-end of the scale to be the judge of. Save scumming is always going to be an aspect of games like these where people decide for themselves whether they want to play it true to the RPG spirit of the game, or roll and reroll the dice whenever possible for the best potential results at every possible opportunity. I don't think its something that needs fixing, any more than a dev could try to 'fix' any other methods of exploitation available to people who play single player games. I don't think a feature like that would be any different from designing your own map/scenario when the game comes out with the editor, and throwing in the best possible items into it at the start for your characters to just walk in, pick up the best gear, and walk back out into the main game. At that point, it is the player who decides how much immersion they want, while it is the developer's trial to give us as much of an opportunity to be immersed as possible, not try to force it in any way.
