Not sure where all the P2W is...

I keep seeing people talk about P2W...but I barely see it.

I see being able to buy some boss stamps, relics, gold coins.....sure this all can push you forward, but you can still easily get nothing but green's - purples.

I've spent $20 bucks and have 2 oranges and all the rest yellows, my buddy has spent like $500 and he's less geared than me.

Is there some item I'm not seeing that's just completely P2W?
