Perhaps this was the same in Ruby and Sapphire, but it never occurred to me while I was playing Ruby as it did when I started playing Diamond.

I have a question about the berries that make your pokemon happy but lower stats. I'm assuming that EV points are lowered; I am also making the assumption that I can regain the EV points, and, more ideally, remove EV points from one stat and then regain the EV points in another stat. I'm particularly interested because I don't feel like raising another one of my pokemon that I feel is fine but I got EV stats all over the place because I was just focused on beating the game rather than making a usable battle team.

SO IS THIS TRUE or is my berry harvesting going to waste :p
