Hayabusa has some non-combo stuff too. If you just watch combo videos, then you'll notice a difference between characters that are good with combos and those that aren't. But DOA5 isn't just about combos. It's about the number of followups, types of followups, how safe you are after guard, how fast a move's startup is, reach, OHs, specific holds, Criticals, hold damage, throw damage, and on and on. It's about bringing those out in each character in a different way, and making each character unique.
