OP cries because there is a new update end it doesn't get delivered with a perfect guide to it. From what I know about the berry system you can get 4-5 berries per slot and you don't have to stand next to it all the time. Once everything is figured out people will just plant the seeds, come back after a certain time and have more berries.
The only thing that concerns me is if the berry price will stabilize at a point where it makes sense for the average comp player to use them, but if that becomes an issue it can be easily solved by tweaking the time a plant needs to grow or the number of berries per plant.
I'm happy over every additional option to farm money tbh.
EDIT: "When the comm was talking about new updates everyone was hyping about Johto starters or Miltoc being implmented , instead what do these lamers do?" Only stupid/ignorant people thought Johto was coming, because as far as I remember the mods always said no one is working on additional regions when asked about it.
