Yeah, I did read your guide which is why it kinda creates the dilemma for future planning.... Looking at your guide, I have the required himes to make a light team works so long I have a Sol, and considering Sol does get an awakening later on, which further makes her more OP. However, my light weapons grid, is beyond abysmal. Imagine a grid full of SRs/SSRs with 0 limit breaks and some MLB Rs.
Cthulhu on the other hand, is because I already have a pretty good team of water himes that could use that one last C frame Def debuff for extra pain, even though my water weapon grid is not as good as my fire weapon grid, but it should be solved in time when i farmed more water SSR weapon...
