It's pretty simple; I wouldn't want to use it in a game where my character was constantly risking life and limb, but then again ... I don't like "risking life and limb" scenarios that much anyway. It's well-suited to a story where combat is more cinematic (ie, characters get beat up sometimes but no one expects them to die). In any case, I definitely like it so far. Maybe I'll use it sometime -- no one was very enthused by my last couple of RP suggestions so I don't know that I'll go with either of them.
