i got Retsu as a healer it says she can heal vangard and assault at the same time, but :
if my vangard is dead she heals only the assault.
if my vangard and assault are dead she does nothing ,not even heal (herself or supporters ) or attack
compared to Orihime Inoue (and Nemu) it says she can heal vangard but :
if my vangard is dead she heals the assaults
if my vangard and assault are dead she heals supporters
so why Retsu can t do something similar ? is it a bug ?
