there's many other uses for the damage scaling freeze bug. mature, chin (unpractical), saiki, athena, terry, k'...anyone who has a multi hitting fireball you can use to start combo'ing with you can do a dm or another ex move after it and suffer from no damage scaling. because mature and athena can actually combo into their stuff, you can have parts of the combo where there's no ADDED damage scaling, but its already BEING scaled since its in the middle of the combo.
so its not just chin and mature. however, i don't discuss this much on the forums since most of the people i talk to go to the #snkplaymore irc on efnet. that and people arent responding on the forums for the most part :p
