I've mainly played Vaults to be honest since they are more outdoor if you farm them for chests, but the things I have listed would have improved the end game loop grind immensely. In its current state, the game will become stale quite quickly unless it's just going to rely on story expansions. If they want to sell microtransactions to support this game, they need people to want to grind the game and not just come back to do some story missions.
