First of all, I have to say I love the new changes to the game such as the troop tree tweaks, the new assets, and the option to directly recruit warbands of friendly minor factions into my army. I have a few suggestions and observations:
1) Currently, Lymbard Squires seem to require far too little experience to upgrade into Lymbard Paladins for how strong the latter are. I'm not entirely sure how upgrade experience is calculated, but I feel like they could benefit from either an intermediate upgrade or requiring more experience to be eligible to upgrade.
2) The Third Legion troops are still based on the old Venetoran Empire troop tree, with the Companion Archers and Companion Cavalry instead of the newer Venetoran cavalry and archer units like the Cataphract and Marksman.
