We do not modify any animal rates so that is not possible for us to add an API for something that does not exist, for the mod issue it should be fixed in the latest update. MYSQL will not be coming to FateUHC 3.0 due to the fact the whole plugin is built around MongoDB and supporting another database would require a recode. We will keep this in mind if we ever create a FateUHC 4.0. We also do not have the ability to change the enchantments that's Spigot related not plugin related. For the lobby and practice locations, they are different permissions
