Heavy:
Wren (PS4) vs. Edna Capone (SH3): His type of fight.
Middle:
Rudy Roughknight (WA) vs. Meru (LoD): Viewing ARMs as basically ITD is good for Meru at first! Bad because it means her Dragoon can't block it. Wouldn't be shocked if he just OHKOs her anyway, her HP is bad. One of these days I need to convince someone to do WA1 damage tests without runes so I know exactly where Rudy falls, but yeah.
Light:
Cyan (FF6) vs. Kahn (BoF4): What Super said, plus Cyan's "fatal status" (Stop, since Death is immuned) is nearly useless for him as it wears off in around the same time it takes for him to charge it.
