I don't understand what you're talking about. Were there a lot of alternate class features for the Limit Warriors that I don't know about?
Eh, the only reason this is a problem is because of how natural healing of nonlethal damage works. I forgot it healed at a faster rate. So I'll limit it so that only lethal damage gives you BP. I don't see a problem with it then, if PCs want to cut on themselves or jump out of buildings in order to get a maneuverspell or two, that should be perfectly okay.The one problem I'm having with your fix is that you removed the part that prevented you from, you know, bashing your head against the wall a couple times to fill up your Break pool. Plus, I prefer a smaller number of levels, but that's just me.
