If I had to sum up my situation in a very simple way...
#1
Use on Thunder-> Potentially able to do R4/R5 Water Accessory with better grid
Use accessories to buff Water team-> ^ for Fire.
Use accessories to strengthen Fire team - >Shit my fire lacks a good carry so triple tiaras don't help as much
#2
Use on Water-> Farm R4/R5 Fire Accessories with better grid
Use accessories to strengthen Fire team - >Shit my fire lacks a good carry so triple tiaras don't help as much
#3
Use on Fire->Finally fire team has awesome carry->Shit, Thunder needs more time invested to do R4/R5.... ->Shit, Water needs.....->Shit, Fire needs......for triple tiaras
#4
Back to #1.
So yeah, it's like a never ending cycle of debate... with a confused boner...
Berith seems very strong, but probably needs a healer to use her for her maximum potential. Without a decent healer to keep her alive while she soaks damage/proc fortitude, is she still worth it? She's still probably a good replacement for Kali, but somehow I just love Kali's design (both art and potential for a fast team) so that too makes me feel kinda not as interested.
I'm also not as sure about committing to Dark, there's like a lot of people do not view Dark as an element with good end-game potential/strength. Well, I'm no where near end-game so I don't exactly have my own opinion on this matter and I'm probably not yet affected?
