I'm thinking of a more detailed tier list that you guys may or may not find helpful and could maybe be used for some battles. It also keeps opponents more packed on a level playing field by having a certain amount of points they can put into their character. Here it is so far (the left number is the points). Things like enhanced reactions and such could all fit into abilities:
