What would personally make me happy is:

Kept pretty quiet for now, but then in 3 or 6 months or whenever the fun of the "experimentation period" has largely passed, more like shifter forms.

It'll show up in logs even now and that's fine, but I think a little period of "Necrodude has a Sparkle Vampire as his greater undead? Crap, I wonder what that can do to me?!" is fun for all.
