And how would you assume users know that the wording of purchasing an item is only relevant for some of them, and not others? By your reasoning it is not expected that boosters that are given at end of season or as a reward generally works, albeit it specifically also mentions acquiring it through a purchase?

Of-course i were not aware that you only apply this reasoning in some cases, but not others, and nowhere via a search engine is there a post outlining the differences that is indexed at google; nor has the primes been sent out so we can search the forums to better inform us of this, if it now exists somewhere not surface indexed.
