You are paying for things that give an advantage in a game. In some that advantage is gainable in the game. In some it is not. In some that advantage is huge. In some it is trivial. But fundamentally it is all the same at it's core. It is the purchasing of that advantage that makes it pay-2-win even if the specific variations and severity differs from product to product.

I fully agree it's worse in other games. Sure, that's a gimme.
