Hi;
IOHO, The Test Breeding feature already is badass.
The trouble with your theory is, in order for the Test Breeding to show "two fake breedings" bred to each other, we would then have to enable the storage of fake breedings
The whole idea of having "test" breedings is NOT to store fabricated BS in the database, so what you're suggesting is that we become a storehouse of bullshit breedings, which never actually happened, which we are never going to do.
Hope this clarifies,
Jack
