Now, I'm not talking about players with no background knowledge of lore who attempt to roleplay. You'll see what I mean in a moment.
I'm hard-pressed to think of more. Now, from that list...
That's all I can come up with. Now, you're probably wondering what those two lists mean. The first is a list, as best as I can sum up, of which characters in Warcraft lore were known to have had some sort of sex due to the presence of offspring.
The second list, meanwhile, are the characters whose children eventually went on to have some of their own. Yep, Arthas, Jaina, and Anastarien. That's all I could come up with. The rest boil down like this:
novel is written by a female author? How this man lives with himself and all his comic books, I'll never understand. But I digress. The children of major characters ought to be given more chances to lead story-worthy lives. After all, the majority of the mothers who birth them don't seem to live very long. Here's another list: This is a list of characters whose mothers either died in childbirth or didn't get to live long enough to do anything interesting that we get to read about:
Due to the fact that every elf mentioned with relatives in which the mother is either unknown or dead, I motion for Tyrande Whisperwind to have a baby. Anyways.
I've heard a few times from a few sources that if you introduce a gun of some sort at the beginning of the book, it has to fire by the end of the book. Perhaps this is true with parental characters and children of major characters; perhaps once they are introduced, they have to do SOMETHING noteworthy. Or maybe it's just a case of author laziness. Whichever the case, I personally believe adding more depth to family tree stories would in turn add depth to the lore itself. Don't get me wrong, Warcraft lore is far from shallow. But imagine what more background information they could give to the past of Warcraft's worlds if we had background on those who lived back then? Things such as technology advancement and social norms would be interesting to know for roleplaying purposes. I know that's just a dopey example, but there are so many stories that could be told. Think about it, Blizzard. There are so many comic books that could be made and sold. Or, if there's enough to go on, books! Everyone wins.
