Not so fast! I was thinking the same initially, but after looking a bit close I going Shields vs. Great Blades is a real choice. My reasoning is this: If you are planning to buff your Grave Guard at all, then giving them +1 to saves should be a high priority, since they are so fragile otherwise. Since units can now only take one command ability buff per phase, that means if you give them All-Out Defense, they get no offensive CA buff. But a unit of GG with shields can take All-Out Attack in
