All legendary's having perfect iv's would be... interesting. It would save a lot of time to get it since people will reset till they get it anyway. It could unbalance things though. I only reset till they have a good nature.

Yeah, there needs to be something where you can toggle hidden power much easier without IVs. Some of the hidden powers put Pokemon at a disadvantage too by lowering a key stat or having to lower their defenses.
