Ok so Blizzard’s explanation of why Kul Tirans are bigger than regular Humans was that they live in a rough place and they have to wrestle with Krakens and stuff.
But that only makes sense in 2 dimensions. You see, physical exercise doesn’t make you longer. Your muscles get bigger on 2 dimensions when you exercise but they can’t elongate in the Z axis because they are tied to your bones, and your bones won’t just grow longer.
So it makes no sense that Kul Tirans are all taller than the world record for NBA player just because they wrestle with Krakens.
Or does it?
You see, I’ve figured how it works. And it’s quite simple.
While Kul Tirans wrestle with Krakens, the Krakens stretch the Kul Tirans.
