So I've been having some discussions with my LS mates, and we've pretty much come to the conclusion that we have no idea what battle regimens do. We've tried several different combination and nothing seems to have any additional effect on any mob we've tried them on. I remember that in some Q&A with SE, they briefly mentioned that BRs have to do with disabling body parts, but I've never seen that happen.
So, are BRs broken? are they just useless? what's the deal?
