Reworked Overjoyed Responses

[TNTMASTER5572]

From what I gathered the maximum chance for a overjoy response is a 5 percent chance, this in my opinion makes it a pretty irrelevant game mechanism in the sense you cannot really control anything about it, just shows up sometimes, I think a better way to go about it is to nerf overjoy responses but, they have a more meaningful chance of happening per extra morale over the requirements(like I don't know the exact balance but mabye 2 percent extra chance per morale over expectations), this would do serval good things for the game, first this would make morale system as a whole less braindead, since it's not just about have enough morale and thats it you can spam get all the skills if you can afford it, instead you would always want to get the highest morale possible and players might give it a secound thought of the morale Penalty of learning a certain skill is actually worth it or not, and would reward a bit more players like me who love to make everything as best possible for my little dupes.
