I vote 2, but it should remain limited to once per game day like it currently is. Making it once per real-world day is kinda harsh for a 30-45 minute event that people currently mostly do for magian trial upgrades for empyrean weaponskills. I can't think of one person I know who currently does WoE for the armor rewards - that's mostly "bonus gil" to the people I know that actively do it. The stuff that's good from there is pretty cheap nowadays for most people to get, and for some other armor, there's better stuff around.
