Why would you need lot bots or super lot luck? You think they're going to keep the global loot pool when reservations are removed? I really don't think they will. The'yre changing it to be more like Abyssea, not more like Walk of Echoes (Which is also supposed to be being revamped in the next update as well)

If anything, it will be easier, not harder, to get currency because you wont be dependent on a bunch of other people to help you get it. And with dynamis being cheap as free, currency prices will go down (especially since the strength of empyreans will limit demand)
