This patch reduces palisade segment health by 20%, and palisade “tower” health by c. 7%. As a consequence, short:medium:gate:long:tower now have a 2:4:5:6:7 (siege and city walls have 2:4:5:6:8) and the health per wall length is now 50 for palisade segments. Furthermore, it makes the costs of palisade towers proportional to their health (cf. D2611/rP23713).
[EDIT] The palisade's inflated <Repairable/RepairTimeRatio> is also removed. As the name suggests, this is the ratio between build time and repair time; template_structure.xml has a value of 2, which means structures can be repaired twice as fast as they are built. Palisades are already built quickly, there is no strong reason why they should be repaired disproportionately faster.
