Tharja and Gaius is a really good pairing imo, Gaius‘s skills and especially Galeforce make Noire a monster, especially if you want to keep her in an archer class. But, idk about Maribelle and Lon’qu- there isn’t a whole lot Lon’qu has that Brady benefits from except the movement skills, and even those are kind of wasted on male healers since they can’t get any of the 8 mov healer classes
