May i suggest to include some kind of extra "stash" system in your 2020 roadmap? For example a lootable consumable hand-radio, that creates a dropoff point for you on the map (so it's a "quest" to reach it). If you get there, you can discard a bag to make it vaulted, and once in every 5 hours, when you die you can choose a bag to respawn with.
Would be some good endgame content to pursue, and i think with the need on the hand radios and traveling to deposit, it wouldn't screw up balance.
