Hmm... That could be true, yes. Well, that does change two things: Awakened beings are more dangerous in the beginning but due to an inability to develop, they remain as they are and grant better chances for the Claymores facing them as time goes by.
Still, it would certainly mean, then, that Clare and Irene would face harder times when Ophelia finds them. However, if they survive the initial clash there's little to worry about later. In fact, now that I think of it, you're stance is more likely. The male Awakened pretty much owned in the beginning of the fight against the Claymores, but it couldn't adapt at all nearing the end when Clare and Miria got their act together.
Ah, well, I have to give in that much. Although it only reinforces my other point: That Awakened beings are beasts; once you get to know how they think (or just act according to their instincts) you are already halfway to the victory.
