I don't know if this is doable, but I think it would be a good idea if the Alchemists could only stay in the rank if they created potions in a certain period.
For example, if an alchemist doesn't create any potions in a week or perhaps 15 days, he leaves the rank and opens a space for the next alchemist to enter the rank. When the alchemist that left the rank creates a potion, he goes back to the ranking with all of the points he had - no one should lose points. And he should continue to create potions to stay in the rank.
I think that would be very helpful to those (including myself!) that doesn't have that much time to play or support of other characters / guilds to create potions. And it would also open spaces in the rank since *I think* some of the alchemists don't play anymore / are not playing on the server right now.
Thank you! ~
