I still don't see myself using it too often outside of ending combos. It just seems like there would be better options (though, the unpredictability might throw some opponents off, if anything).
Well, for my main oki game, I'm currently using 2B (anticipating rolls towards me) and 5D (anticipating rolls away from me). From my experience (which, granted, isn't very much), it works better and isn't reliant on CH.
