In short - "It should make sense when I think it should, and it shouldn't when I think it shouldn't!"
All that rant to switch between other games and this one. Then more rant about about "what I think is the right thing and how others are wrong."
People have already described what kind of game they expect from RNG, and that's why they support RNG. Saying "do whatever you want" is basically "fck you for supporting me, I'll do whatever I want!"
Just the type of mentality you need when you want an outcome such as "Devil Is A Part Timer" Manga.
Sure you can do whatever you want, just don't blame others when the game takes a dip and many players just decide to leave. Of course you wouldn't give Sh*8, but I wonder how RNG would fee about alienating a good amount of followers!
