I feel like there is an easy fix for the solo content conundrum. Just put scaling onto activities so that if you go in solo, or in a duo, or whatever the content scales up to the challenge. Conversely, they could create something akin to the nightfall cards that allow for modifiers to be applied by the player with appropriate loot drop quality to match. I also prefer solo/duo for activities and would love to have the ability to scale something to my fireteam size and by applying scaling or modifiers content gets designed for everyone. Raids shouldn't be messed with, that's a very specifically designed activity. While I would welcome more solo/duo content in the game, I think we have to think realistically now that Bungie has separated from Activision so they're resources will be limited. Combat scaling would be a useful compromise I feel. I would also add that it would be awesome to replay the main story and forsaken missions over with skill modifiers with updated loot drops to boot. I know we can play heroic versions of the missions but I would like to play from start to finish again.
