One modification that I really enjoy is that activation is a touch easier to succeed with in The Pikeman's Lament than in the earlier Lion Rampant. A simple move activation is often passed on 5+ on two dice, with a further +1 on the roll if your Officer is close enough.
That is an excellent addition. When we played Lion Rampant we gave the Leader the special rule that allows a re-roll per turn to\ any unit within 12" (I can't recall what the Trait was called...). Leadership is important!
