Proposal: Remove the defense bonus to woodsman and instead make it "you gain +10% CS when in rough terrain"
Rationale: The woodsman promotion is neat but rarely used because you are giving up the raw combat power of a straight CS boost. Its also a deadend promotion so you have to really want to commit to the power. Further, the defensive power of woodsman is a bit in conflict with double movement, generally you want your attackers to be mobile, while your defender stick in a space and hold an area, but then you aren't using the double movement.
Making it a simple +10% CS in rough terrain gives the promotion solid power with some offensive and defensive potential.
