Okay, allow me to rephrase in that case. There is no METHOD OF ACQUISITION within the game, and by putting it on the cash shop there will with 100% certainty never be.

Your certainty of a method of acquisition not coming into the game without the cash shop was 99%, remember? You are in other words saying that without the cash shop there is a slim but PRESENT chance of getting more things to do IN THE GAME to get stuff.
