Tweaks to Form Coalition
Added blockers to events that form relationships to not allow friends to became rivals or the opposite

Localization polishing

Since warfare is now harder, its necessary to slow down peacetime development:
-> +20% Base Building Cost
-> -10% Base Development

Less acceptance for vassalization for every ally the target has (as they already feel secure)

-> New Interaction: "Form Coalition" neighboring small counts and dukes, specially if independent, can form alliances to protect each other from common threats.
(this is also part of the slower expansion balance chantes, to make the game more historical and less map-painting)

Changes to War Taxes modifiers and Designate Heir costs

-> Changed the realm size debuff from -30% to -50% taxes/levies on max stack (this can be countered by the new Realm Laws)

-> Slower Fabricate Claim task from Court Chaplain (average of 7 years per claim)
(Part of the "Slower Expansion" balance changes, to make the game more historical.)
