Tactics for the Swamp (Fortress).

Alicia was upset. It's not right. But never mind, that's not the point. Lately, I've noticed (although it happened before) that my Swamp creatures just don't move around much. They barely move. Even though their logistics and pathfinding seem to be working. Even with boots or gloves, they still lag behind compared to other units, even with all their other advantages. Although, as was said before, Swamp units don't have a movement penalty when moving through difficult terrain. Right?
