I hope we'll keep seeing more variety in families added as premades in upcoming packs: gay couples, single parents, multi-generation families, etc.
Though I'm sure we won't get families with both pets and children in packs that aren't C&D. Or any possible other packs that might include other pets.
For me, including *any* LGBT Sims and families is the message and it's a good one. Is it uneven right now? Yeah. That doesn't mean it's going to stay that way. And even if it does, I don't believe keeping count is helpful.
(also hey, if we could set attraction for individual Sims, that would be great)
