I agree...and most of the value people place on 'flawless' isn't because its rare...its because they can be really time consuming to get...and ill tell you what, that 0 atk took time. Definitely my most time consuming breeding project yet. I got a ton of 'flawless' with attack before the rng saw it in its good graces to grant me one.0's to me are a special breed of flawless when something is 31/0/31/31/31/31 or the physical version of that. I consider it 6 IV's in the desired spot because it's useful for swapping skills and Foul Play. Standards are just 5x 31 in the correct spread with relevant IV's. I even went as far as to do 31/0/31/0/31/31 on a few specific Pokemon I've bred.
I also got one with 0 atk and 0 spd but I don't have the patience for that right now.
