An uncommonly known fact in this game is that MZ has better rewards for younger castles. On almost all events recently, farm accounts lvls 11 (relatively) and lower that are less active have much better rewards than accounts that are actively played lvl 15 +. This can have a few implications:
Personally I don't have a farm, because I don't have patience or time for them. But, I would encourage anyone who does have time to make one. A lot of people have told me they really don't take much time.
Enjoy!

P.S. I'm in a great mood today. You might say I feel like this man.
