That is not a loli, that is a child. Don't get me wrong, I agree: the children Miqo'tes are absolutely adorable and I want to smother them to pieces from what I have seen. While this game is very tame in the "adult" related content, there's just enough stuff that if you took a child character through the game people would probably throw a hissy fit.

Not to mention the eternal bonding aspect of the game. If this character type got locked out of EB people would cry out "unfair!". If they weren't, well...that opens an entirely different can of worms.

Luckily you can currently make female miqo'tes pretty close to her if that's the look you want.
