>>26788540IVs are cool in concept, but they end up being the exact opposite of that Pokemon even stands for.
You're supposed to grow strong bonds with your Pokemon and battle with them to make them stronger, which is what EVs are more closely related to.
To get the correct IVs you have to breed Pokemon that you will possibly never use again over and over until you get what is considered "the best" instead of what you were holding on to for your journey.
IVs only affect competetive fags and changing them to something else "like slight coloration or size differences" would not only fit what IVs were supposed to be in the first place I.E. Pokemon DNA and would make catching and training your Pokemon feel a lot more personal.
