Can't we all just agree we're all after mammoth mammaries but for different reasons? Let us agree to disagree. And I'm not trying to force an upsize on anyone! Choice is exactly what I'm advocating. If someone, during their character creation says "Hey, can you take a little off the top", they should have that right. And by the same token, if they want to say "SUPA-SIZE IT!", heck they should have that option too.
And since we're all preaching realism, there should be "special animations" for splashing in cold water, exploring the icy Tundras or having Frost cast on us. Maybe a status icon too, like "Extra Perky".
