Compromise: A possible solution
Let players have their cake and eat it too
Alchemist potions suck, especially compared to food (30s vs. 1800s duration), But what if Alchemists could make Fantasia Potions.. They are potions right?
I came up with a solution while staring at that lonely Behemoth Horn in my inventory and dreaming of that Super Armor you get from the Odin fate.
What if the ingredients were from multiple Rare Fates & items that only pop once in a while? like, what if you had to work at getting each ingredient, but also knew you couldn't just Grind like Mythology stuff, you had to do whatever Astrological Voodoo gets people in the right places at the right times.
This keeps Fantasia almost as rare as it was before, but it also gives Alchemists a reason to continue playing the game and paying subscription. Let people both buy and make the thing, but let making it be the most cruel recipe ever.
