Imo the problem here is that not every activity gives the same amount of gold / reward and therefore they time-gate them so you can’t just farm one thing all day because it’s the one who brings the most (FZ-W1 / W2 Farm | Boss-Farm | SAB Farm… …). You complained about how nothing else is time-effectiv compared to XYZ Farm. Now you complain that you can’t do it more than once a day…
Think about it.
~just my 2 cents~
