Bayonetta as a "combo" character is very, may I say, superficial. There seems to be very little depth in her gameplay as most people just go for the same ol' 0-to-death (or something%). At least she can combo, so that makes her a combo character, but mostly you'll see just that one combo.
This (as in playing against Bayonetta) will just make the fight drag on - unnecessarily so - since you pretty much have to camp, if you can. I mean, have fun camping with someone like DK. She may (and is) beatable, but that doesn't mean there was nothing wrong with the way Bayo was designed. Because there are plenty of things wrong.
