I don't understand why complicating the species clause is such a big deal. The way I see it, we obtain a more enjoyable metagame in exchange for a more complicated clause. It may be complex, but in the end I think it can only benefit us. Is our aim not to provide the most enjoyable metagame possible for the players? I honestly think that this outweighs the fact that the Species Clause becomes "uglier".
Pocket, I don't understand your second point at all. I would have thought it was obvious how similar Latios and Latias are to eachother; they are as similar to eachother as the Giratina formes. Think about it! One takes a more offensive approach, one a more defensive. It's just an example anyway. I didn't mean it the way you seemed to understand it, of course they're different Pokemon, but they're as different as some formes are to eachother.
