Not at all. :) Like all gimmicks in systems, there is a very precise way at defeating a shape shifter. I even pretty much gave away to you exactly how to beat one which I probably shouldn't have, though if you think about it for a bit it'd be obvious enough. And Alice could probably describe even more ways of doing it. Shapeshifters like many other things have both strengths and weaknesses. Admittedly, facing one for your first fight was probably a bit much.
