I second my opinion. Would also like this as an option rather than transforming myself. Plus, I think just the one time event interaction with *whichever you choose to bond with* (in my case, I chose the symbiote) is kinda sad when there are no future interactions.
Also, I like the idea of monsters doing *you know what* to me, too^_^! (Though I prefer being in charge while they do me, heh heh)
