Better Early Regulars
This mod increases the professional Regular army unit sizes in the Age of Renaissance and Age of Discovery upwards so they are competitive against levy unit sizes. Infantry Regulars are increased to 500, all mounted Regulars and Auxiliaries to 250, and all Artillery to 100.
As Regulars have a +125% damage bonus against same-era levies and +250% against previous-era levies, that means a Regular is 12.5% better than an equivalent same-era levy unit and 75% better against a previous-era levy equivalent, even though they engage with fewer soldiers per frontage.
This only applies to units already under that cap. Normal regular sizes surpass this in the Age of Reformation and no longer need adjustments to be better than levies.
Upkeep per-soldier is the same, but upkeep per unit is increased with their size.
This does not apply to Age of Traditions regulars because the starting manpower building can’t support it, and it bugs the starting maintenance.
