What's the deal with yordles?
I've always been a fan of the "little" races in most games - gnomes, goblins, asura - but they generally follow some sort of rule for how they look. Now, I like the variety of yordles in LOL, but I don't understand how their taxonomy works.
Why are some of them furries, and some of them look like humans? Why are only the males the most human-like, while the females have blue or purple skin? Is Heimerdinger furry, or does he just have an abundance of facial hair? They're cute and diverse, but I don't understand it. Please help.
