Currently working on my own unit pack right now for FotS. If I intend to release this publicly I do recommend having all Unit DLC packs because a few units from DLC are mixed in with weapon models from other DLC and its also to avoid copyright. At the moment I hav two units only exclusive to pro-shogun clans.
Tetsubo Metsuke who beat their enemies into submission and a small light cavalry unit consisting peasants (reused the same model from my unreleased peasant unit) armed with firebombs.
More to come.
