Ev'd all of my Pokemon. I'm traumatized saw my beloved Meganium had 154 attack stat while its spec attack only 120. Since then seeing my pokemon growth properly=fun. EV training not that bad in my opinion, its add little fun for me. I also have Pokerus in my platinum, it will be a bit foolish if i'm not ev'd train my pokemon. But never do breeding, nature, IV, or anything random like that.
