I know; that’s just my way 
There’s nothing wrong with playing the game however you want; there are various ways to play and many different goals you can set yourself.
I understand not having such high criteria as 90%+ IV, but I don’t understand using rare resources like stardust and candies in lower IV Pokemon because it’s pointless. You power up to battle... and there’s little point battling with poor IVs. And if you’re not battling, you shouldn’t be powering up.
That’s not aimed at anyone though because nobody has actually said they do that; it’s just an addendum to my previous comment.
