there actually is an NPC that'll tell you in vague terms whether or not your IVs are perfect or not, but i don't know where he/she is
That's what I had in mind, or at least whether he plays competitively, not that you would care to realize that.
it's just silly to even assume people know what IVs are in the first place
it's only the most esoteric thing ever
I though IV's were pretty common knowledge to everyone besides the most "casual" player
Bothering to do anything with them is a different story
Well my cousin's a really casual player.
Just destroyed my cousin in pokemon ama
