Also, people, don't forget about just attacks (attacking in a rhythm, when character flashes red). The boost in damage is awesome.
It's basically like what you had to do in PSO to get a good combo. I ran into some people back then who for some reason could never get the timing down and just always mashed the attack buttons. I tried to tell them they could improve their damage and accuracy if they timed it right, but they could not understand or didn't care.
Craziness.
