Suggestion: Keep most iron missions

Part of how Iron Missions engaged the player and encouraged active play was, we could look ahead to the rewards offered for say Iron 5 of a given mob and decide to grind out 1 through 4 not for their own rewards but to get access to 5. In the switch to Codex, those of us who began this project and have not completed it, are left in the lurch. Codex is a good step forward, but please return all of the iron missions to their terminal, just don't make any of them repeatable any more. I would like to finish not just Iron Merp 3 but all of the Iron Merps (just as an example).

And for God's sake don't just terminate all irons at some arbitrary date! Let us finish!
