Well never mind then!
I mainly had the idea when I considered I take 2 demi-gryph characters, and then I thought about putting them in the one unit, and I realised that it would cover 4/5 spots on the front rank.
That said, it seems like a very sensible way to protect a warrior priest, witch hunter, or some other character who can bring buffs to a unit but we don’t want to fight. In that way, you don’t need to give them any equipment at all to keep them cheap.
Interesting…
