But if two parent have the Same IV as 31, It will be no longer random. And every pkm are the same when you have enough money to breed.
Look at the list pkm of the global trade link. All top pkm are 5x31 IV, right nature, right ability two. All are same. It look so bore.
If they make a little bit random IV when two parent have same max IV like I sugest before -> the system breedind will be more interesting, all of pkm will have a little bit different but they are all strong enough with 2x31 IV and other IVs values will random from 21~31
