How would you improve Teens?

I voted both. Though I do believe Parenthood took care of exclusive content (don't have that pack). But to me it seems in a life simulation game something like that should have been taken care of in the basegame. They failed to do this with Sims 3 and they failed to do it again in Sims 4. I just don't think that's right. And other than that, I'm one of those who think they should be shorter than their adult version.
