I'm finally seriously playing Senran Kagura SV.  Having played through most of the Dynasty Warriors titles, Senran is NOT the same button masher as the DW series.  It's BETTER.  The combat is deeper and takes a fair amount of quick strategy.  The problem is that I'm consistantly finishing missions with a "D" rating, and that's not referring to breast size.  I do know that I have to finished a mission as fast as possible while taking as little damage as possible to achieve an "A" rating.  But I have to resort to a fair amount of grinding to level my character high enough to do so.  I'm sure this is part of the process.  But can anyone give me any battle tips to help minimize the need for grinding?

Not cool.  I have to share my controllers with my daughter... when I'm not playing Senran.

I've been touting it's depth in almost every comment I've made. Guess you weren't paying attention. No tips. I have to get back to it myself. I played it intermintently, didn't focus, forgot techniques, and started getting my ass handed to me.
