Unfortunately (or maybe fortunately) Elyssa is not vicious enough to give Amanda exactly what she is giving. GM, Judd, Spencer and maybe Aaryn would have no trouble going toe to toe with Amanda and fight. Elyssa is a "flight" type person as she doesn't really have it in her to be cutthroat.
I have been rooting for Elyssa the entire time, but at this point I am rooting for ABAM (Anybody BUT Amanda/McCrae). It's not a perfect ending, but I'll take it.
