I had a unit of Thracian MF offensive spear holding a flank straddling a piece of brush and plantation. There are enemy cavalry and heavy foot lurking around but on the first opportunity they charge out of their perfectly reasonable defensive into the open because they were not wholly in rough ground. Doesn't matter that they were 90% in rough, or even 99.999% they still have to test to not charge.
However, if the precious Heavy Foot(are you detecting a certain bitterness here
It's hard enough to get terrain down for your mediums to operate in but it does appear somewhat skewed to get them out of it whilst the heavies have the choice to go in or not.
