This fight in story mode, the one with Raw Nerv Parawheel and Primed Parasoul is just too restrictive by only allowing 1 bronze fighter with the set in stone characters. I've hit all the defense brackets for the highest bronze I have left, In Denile Eliza and she's only reaching up to 1235. Even with a 21% defense boost and 367 health boost via skills, all it takes is one Pinoin Dash/Violent Grudge to take out half the meter. And it's not like I haven't beaten other matches in an undermatched level, I've beaten other story mode fights with strategy where I've been about 33% of the ai's levels. But in this particular case, as long as it took to get to this point in the game I've got no options to advance because even if I try to buff up another character it won't be as powerful because there's no way to get keys outside of top tier of the prize fights. This fight seems like it should have at least 2 slots to pick, otherwise there's no way to strategize around the reaming of those specific attacks.
