Humans and elves reproducing?
They are not even from the same lineage.
Humans descend from robots, elves descend from trolls? How do they have kids together?
Even worth is orc and draenei. Garona is supposed to be this but they’re literally from different planets. Orcs evolved from rocks, and Draenei evolved from the unholy union of a squid and goat most likely.
At least orcs and ogres make sense they’re fromt he same lineage.
I’m gonna have to go with “magic”.
With a side order of “magic” and some “magic” on top, and an extra helping of “the Titans did it” (through magic).
It was very holy thank you very much
You see when a mommy and a daddy really love eachother then they share in that love 
You win the internet! Hands a cookie and a free t-shirt
I came here specifically to see if someone would use this gif, and you did not disappoint! <3
Oh… wow. I didn’t have a speech prepared or anything. This is just so unexpected. I don’t know what to say. There are so many people to thank. I… I promised myself I wouldn’t cry. *Sniff. * Damnit, Rakham, hold it together.
You’ve seen the fanart of it, I see.
Because reasons.
That’s honestly as close to an answer as you’re going to get on this one.
You are literally red from the unholiness.
She just has the hots for you.
Just don’t read the fanfic.
Because all organic life is connected through the Life domain and thus develops down similar pathways.
That’s why we keep seeing the same shapes turn up, like wolves existing in more or less the same form on Draenor, Azeroth, Zereth Mortis, etc.
It’s as good an answer as any, you’re welcome.
Shoulda let me and garrosh see if we can make gnorcs
Ohh god do I really need to explain how reproduction works
Around here… yeah. 
I hate that this makes a kind of sense in the context of the Warcraft universe.
Like I said, you’re welcome.
It’s probably the only rational answer anyone will come up with in this thread lol
