I would be strong and continue to adapt and become stronger. But I would need to train more to truly become "broken". I won't see myself as broken yet.
Why vaewolf and human/nephalem? favourite hybrids?
We could become broken if the threat which we survive and adapt is broken. I swear when i read "hyper-adaptable" the picture of mahoraga come to my mind.
Adaptation may work not only on transformation basis, sometimes your stats just increase, these physiologies seem to have big potential to grow in strengh with out need to transform.
