"Oh, what's that? You've got a zapdos? Nice trophy, there."
What do you think event Pokemon are? Do you think Nintendo or other companies catch a single Pokemon over and over? That must be why it's taking them over 2 months to release Arceus! :p
And what's the point of us rnging the same Pokemon over and over? The end result is the same thing. Also, that would make it impossible for me, for example, to distribute one-time event Pokemon like DW starters because they cannot be bred.
I understand where you're coming from, though, but each Pokemon is nothing more than values in a .pkm file. While I wish each individual Pokemon was unique it's just not so, even their "personality" is determined by a number.
