Hello fellow phalanx enthusiast!
There are some technical problems with the currently uploaded modpack:
1. The db tables are not in a db subfolder, which means nothing will be loaded at all.
2. To successfully remove formation attack, you have to rename "EF_DeI_unit_attributes_to_groups_junctions" to "DeI_unit_attributes_to_groups_junctions" so that DeI's table is overridden outright.
3. For all the other tables to load after DeI, I would add @ to the beginning of the table name ("EF_Bar_land_units" to "@EF_Bar_land_units", etc) to ensure the changes are loaded last.
As for the gameplay:
I definitely noticed a nice Rome 1 style force-field with the enemy fruitless trying to come to grips with the phalanx.
Pikemen grind up light units like hamburger... but they are unable to inflict (any) casualties on heavy units.
In a battle, my white shield pikemen could not kill a single Getai Ordesci (elite swordsmen) after 10 minutes of combat. Of course the only casualties the Ordesci inflicted were from a few lone wolfs who got in among the formation.
I know that if you just increase the length of the pike and nothing else, they will steamroll any unit in the game in a minute or two.
