Review Detail of traceeee in DxD: The Plunder System

I really like having a shinto champion for the mc I think it's the first time i've read about it hopefully in addition to cannon events i hope there would be new Shinto events or AU events. What I didn't like would be the level system I think it was a bit to much and could've been more simplified when i think of S rank I would think something about elite not high class and really the abilities of some character were to much and I feel like they don't deserve it. Also mc isn't really abusing his plunder system when why doesn't he challenge others for a fight/spar and i think he is saving to much points when every time he faces someone new he just distribute almost the same amount of points to usual stat I think saving 100 then boosting it what you really need to surprise enemies with sudden increase of strength or speed or perception.
