Hello,
I know that without WoE and castles, the guild investment system might be pointless. However, I'd like to suggest adopt the system in which we could trade MVP drops for Cats Certificates, and from there, convert them into Thanks Invest Certificates, as described here : https://irowiki.org/wiki/Guild_Dungeon_Investment_System
I believe by implementing the certificates, we could supply the already very high demand of mats for brewing or cooking, such as Savage Meet, Ygg seeds, +10 foods mats, and even blue herbs.
If for some reason this suggestion cannot be implemented, I would really appreciate if the staff could consider a solution for the shortage of mats for cooking/brewing.
Thank you so much in advance
