re: hitstun
there are characters we think need less, becuase they have too much. There are also those we think have too little and need more. There arent any that have relatively little and need less on an absolute scale, nor are there any that have a lot and need more. Thus, if we decrease histun slightly, those that are affected a lot will have a larger absolute decrease than those that have too litle, even though the relative decrease is the same. Therefore, once we find the right value, a slight hitstun decrease will make the heavies more viable by decreasing their combo-fodder-ness, while doing little to harm their string-based games. Also, there are very few staple combos that will get harmed by this slight decrease - only stupid things like snake's triple utilt combos or yoshi eggs comboing into themselves will be weakened.
