Review Detail of MajorLove_Gravy in Fate/DC Universe

Does anyone know any similar stories? as while I love the premise this story is kinda ass. I hate the mc and the system is boring because it isn't random which I think would make the story much more interesting. I also don't like how weak overall the mc is and while sure he has the potential to be OP but the system is made in a way for him to only be op when the author wants him to be. Also the way the mc handled the whole nabu thing just felt... cringe? like in those Chinese cultivation novels where mc has to have people congratulate this young master for doing good and always one step ahead of everyone else without explaining himself so he can be smug
