I can't tell how to decide which stat a pokemon doesn't need. Couldn't google up any IV spreads or suggestions. Breeding for 6iv is a pain, so i'd better go with 5iv instead. But how do i tell which stat is not crucial? Does it depend on pokemon itself in general or by the nature you chose? with -10% being not crucial? For example if i want a 5iv chesnaught with impish nature, do i go with 31/31/31/x/31/31, as Sp.Atk is lowered by nature anyway? Or it's vice versa and i'd better compensate by having a 31 in Sp.Atk instead?
