Well in FKG I don't really bother ranking any girls. Every 6* girls are strong and usable with some capable in broken maps more than others. Counter teams happened to serve as 'Jack of all stat, master of offense in form of defense' This team has high survivability and if you don't know, counter damage and solar drive penetrate defense. The damage becomes consistence and you can just use 1 team to blow many challenging maps away. But don't expect to see super fancy numbers like nuke or crit team.

Saffron is regards as the best tanker in the game due to her perfect synergy in abilities set. She possess 'the trinity' defense skill. (Dodge+Counter+Guts) Equip Provocation on her and you will get not just fortress wall, but a fortress with battalion cannon full stationed that ready to blast anyone who try to breakthrough.
