So we all familiar with the passwords we can input in the beginning of the game to add some flavor to our runs, yeah?
I came up with this password that I would like to see added in the game, the reason why I am suggesting it is cuz I really like both Reborn and Rejuvenation but it gets really hard to pitch it to other people since, in order to beat, it's almost required to have a full team with good IVs, EV trained, with the correct Nature and Ability so, a lot of times, the story gets halted because you get to a gym battle where your need to change one or two (if not all) members of your team in order to pass it and breeding takes time and requires some know-how, sure you can use debug mode but I am sure a lot of people, like me, feel "dirty" when using it even if it's just to fix IVs, EVs, Nature and Ability and would rather not have to resort to it at all.
So what does this password do? These effects combined:
ALL Pokemons (Wild, Trainers, Bosses, etc) come with 31IVs in each status.
ALL Pokemon have 85 EVs in each status.
Nature is set to either Docile, Serious, Bashful or Quirky (Natures that don't increase nor decrease any status).
Remove items that either increase or decrease EVs.
Remove the "Pokemon Psychologist" NPC (The guy in the underground that can change your Pokemon's Nature).
The Move Relearner can now teach Egg Moves.
Disables Online (It's a mode just to pass the story without having to worry about the grind anyway).
I hope I can see something similar to this in the future, it's just a suggestion tho'
