Personally I'm not against sizable boobs either, then again, most people probably aren't. But I agree with the general notion that despite size, the shape should be somewhat realistic, and there should be the option to have smaller sizes. I agree that especially on the aurin, a smaller chest would seem better for their lithe frames. For draken or especially mechari, bigger sizes seem to fit more. Plus, the mechari are metal, so gravity defying boobs are very much a thing there That said, a natural shape and a good slider distribution is what I can easily agree on as well.
