There will never be a constructive discussion here besides encouraging people to express they want the rewards available again then wait patiently to see if it happens. Realistically good information here eventually does make its way to people on the dev team where it matters.
One problem is this isn't a forum for discussing exploits. Even mentioning them is advertising them, so we can't be very explicit talking about them and that leaves room for disinformation. It's not necessarily a bad thing, because this forum shouldn't be about that, so it is what it is.
Ignore people who say returning these rewards is somehow bad. We're still playing the game and playing more in the future for old rewards is a good thing. Moogle Tomestone events are very popular because they return exclusive items from years ago and lots of people return for them.
