That makes little sense to me though. On DMM they have daily revivals of unit farms and unless I wasn't paying attention they also have a 100% first drop, with all the unit farms. Unless they changed coding significantly enough to be considered a different event altogether I cannot see why 100% first drop can't be achieved with a standard unit farm revival (even MC revival) here.
