Thing is though, that the new morphs keep the market going. If we started working with only what we have now, prices would drop a lot and continue to drop as more and morphs and combos were available (don't get me wrong, I'm not one of those people who complains about dropping prices). So in order to keep prices up and some of the breeders going, they want to discover something new.
Now I completely agree that there's probably too much importing and some people too desperate looking to get lucky and find something new. My point is that so long as there's money to be made from it, the imports will keep coming in. And as more and more people get into the hobby and start producing more and more and prices of what we have now begin to drop, there will probably be even more of a hunt to find the next big thing.
