>>14812041I would suspect though that Destiny Knot may conflict with the Power item and just select it in most cases anyway so the chance would just be increased minimally, and as I said, you give up control of the Nature which is generally bad.
Besides, which poké needs perfect in all 6? You can generally sacrifice attack for s.attack and vice versa or speed for anything if it's slow already.
I'm pretty sure that's why Destiny Knot is 5 IV's and not 6.
