Autoresolve Equalizer for AI factions

This mod does 2 things:

1 - Reduces the bonus to auto-resolve that the major/playable factions have against the minor ones, giving them a better chance to survive and fight back when they can.

2 - Reduces the "Shroud" bonus that happens when things happen in areas currently unexplored by the player. Note that this is for first time exploration. This bonus doesn't apply for areas you have been to, but lost sight of. (In vanilla, advantages given to a faction in auto-resolve gets doubled when they occur in regions unexplored by the player)

This should allow more instances of a minor faction being able to actually get victories when engaging major factions, tho major factions will still have an advantage by default. Reduced situations where a minor faction loses an entire healthy army or more, to a random undefended major faction settlement.

Be warned that this may slow down the campaign progression of major factions.
