I think rewards are time gated in FF14 to maximize player life with the game.
I spent the longest time in Void Ark trying to upgrade my law set on some summoner i never play. Ended up with my full right side in eso and i started on the left side with only the robes from void ark. Boots dropped today though.
My luck being that bad in Void Ark i switched. I went to work on Yo-Kai because i figured it was a limited time event and there was no real pressure to complete as long as i keep at it. 13 fates, 2 legendary medals with 4 weapons to go. I'm sure because i clear the regular medals between weapons.
A horse might go for the carrot on a stick but it would only take so long for a human to stop trying. What am i supposed to think here?
