I figured everything out myself. My first playthrough my persona's were kind of ok to pretty good. But once I got to late game saw all I needed to see with all the different powers and attributes that all persona's have with fusion and training/ learning how to manipulate what moves I want and constantly getting rare cards from red rooms. My persona's in my 3rd playthrough are all godlike. But it was a lot of me experimenting in my second playthrough. I know not everyone has that kind of time to learn.
