It felt like a lower priority class for 4* for me.
I don’t use Sabina anywhere near as much as Proteus, Wilbur, Boldtusk, Grimm, Melendor, or Scarlett.
By contrast, Thoth-Amun will go on my Defense, and be of likely frequent use for raiding in purple stacks that Sabina already never comes along for. (I prefer Proteus, Rigard, and Tiburtus currently.)
