I don't care, but as far as my team goes, it has to be males. Unless I decide to use a pokemon that looks feminine, in which case, that pokemon has to be a female. And, of course, if the pokemon is genderless, it's genderless. Duh.
Back in Diamond and Pearl, I would only have Pokemon on my team that matched the gender of the character I played, whether it was Lucas in Diamond, and Dawn in Pearl. But I swear to god, when I tried to breed perfect teams in those games, I would get strong opposite genders and it drove me mad s*** insane, so since platinum, that tradition was thrown away
Let me make this crystal clear; Ruby and Sapphire remakes are coming this generation (gen 5). Get the hell over it.
