Hee-Ho

I just started a new playthrough of Revelation with the Unofficial Gay Fates mod and a patch that allows same-sex pairings to still produce their child units. Bearing this in mind, what would the most optimal pairings be, now that all pairings are possible?

Not really. I made sure to have Galeforce for Morgan, and I'll probably put it on Severa as well

I'm on chapter 15, and I currently have the paralogues for Owain, Yame, Brady, Severa, and M!Morgan available, but I've been refraining from doing them for now because I wanted to know if there was an optimal time to unlock the 2nd gen units. Does it make a substantial difference if I wait? Or should I just get the 2nd gen as soon as possible?
