Okay, I've played P4G to completion and now I'm half way through P3 FES and I'm a little confused as to the point of these. I get the point of having reflect or resist on Hama / Mudo skills but what does the weakness actually do? I figured it would make it a guaranteed insta kill, but obviously that doesn't make sense since then there'd be no difference in the tiered variations for those weak to it. Plus, I've missed already against shadows weak to it. Is it just there for show or does being weak to light / dark actually change anything pre Persona 5? Thanks ^_^
