Comment on “Magic in Mass Combat”

Regarding anti-magician sharpshooters: is that a potential candidate for inclusion somewhere in, say, the Fighter's sage abilities?

I don't think it would be much fun on its own, but as a rider along with some other skill related to, I don't know, military expertise for the purpose of raising a large army, or something.

Or maybe it's just the kind of thing the players will learn from all the times the enemies do it!
