I want Rommath to have a daughter so she can run off with a some random orc, permanently triggering @Friendlyimmolation.
On a more serious note, I'm not as much for characters just having random offspring that show up in-lore/game later as I am actually developing already existing child characters, like that human orphan that wanted to be a druid or that orc orphan or Salandria/Dornaa.
I would imagine they should be around Anduin's age and seeing as one wants to be the first true human (Well Stormwindian) druid and Salandria/Dornaa have a dragon prophecy looming over their heads in the future, I want to see these characters grow up and do something.
