Yup, that alchemist reset is really helping new and small guilds get ranked... wait, no now there's just two of the same guild on the list.
Alchemists resets are important as it means that alchemists need to continually craft in order to maintain their place on the list. If we did not perform any resets then alchemists from eras gone by would present a mountain that new alchemists would struggle to over come.
I think that may be helpful to all guilds as it allows other alchemists to take over pot creation duties without the need to always use the same character just because it is the ranked one.
As far as I can tell most guilds try to have one or two alchemists creating potions which is just fine. But that does divide their resources and possibly hurt their ability to climb the list. If they want to risk that, that is up to them.
