Yeah, I'll probably just keep an eye out for 4x31 Dittos regularly, that's the best I can do.
Really, it would be enough if genderless Pokies could breed with their own species - it would make way more logical sense and allow for a properly planned breeding process...
... and thus, most importantly, it would also make genderless Pokémon like Starmie more popular and accessible, most of all to people who are very competitive and insist on their natured 5x30/31s = good for healthy variety in the PvP scene.
Really, there's no reason for it to not work that way.
It'd be beneficial to everyone and the game itself, with no downsides. :/
PS: Though I'd definitely exclude Ditto from this... that'd be pretty broken.
