COnsidering claire is not even awakened yet , it's probably her for now. After AW/SAW , claire might actually have a different use (she can attack 3 targets at once) , but right now shes just a gold archer with attack increase. Spica is a plat archer (and an elf at that) with attack and range increase , so for now , she's a direct upgrade.

Bashira is a burst archer. Shes good vs bosses or stuf that needs to be killed fast. That's a different niche , and that's why i'd keep her in the team over claire.


PS ; the gold male healer is quite a bit weaker then iris as well , so at the very worst , id get iris instead of him if camilla is not cc-ed
