One could just as easily argue people are "giving up" on many VWNMs because they are slowly but surely getting the actual rare drops they want and subsequently having an ever-decreasing number of targets worth spending stones/dust on. It was fear of this that probably gave rise to VW drop rates as we know them to begin with.
If we've seen more Qilin shouts of late, it's because pouches are always going to be worth money.
