This thread is for discussing changes as well as providing documentation for what the mod changes. The top level post will always include all changes in the mod to date.

Table by table list of changes with reasons for each.

Release Version 3:


(cai_diplomacy_complex_treacheries_tables)

Increased the number of turns between breaking a treaty and declaring war without a treachery penalty (military access 5->10, coalition 5->15, alliance 5->20). Shouldn't affect you if kicked from alliance/coalition rather than left.

Reason: More long term gains for treaties means more consequences for breaking them

(cai_diplomacy_deal_evaluation_deal_component_tables)
Distance in a war is now a positive factor to call for peace, not a negative factor

Reason: Fighting distant wars with threats in your backyard makes little sense.


(cai_personality_diplomatic_attitude_components_tables)

Increased negative ramifications by ~0.3 for all personalities for hostile actions against friend.
Increased negative ramifications by ~0.1 for all personalities for friendly actions vs. enemy
Decrease positive ramifications by ~0.15 for all personalities for hostile actions against enemies.
Decrease positive ramifications by ~0.2 for all personalities (except default_late and resentful_late) for friendly actions vs. friends

Reasons:
Warmongering is viewed quite poorly. Makes war declaration even more meaningful. Also offsets some of the positive gains that declaring war would bring to enemy of enemies.
While wars and treaties relationship changes are working well vs. target faction, they were creating too many friendships in the game. This lessens that while still retaining its importance.

(cai_personality_diplomatic_component_values_tables)
Remove war malus
Non-aggression pact: will be worth +15 after 40 turns (was 10 after 20)
Military Access: will be worth +25 after 40 turns (was 15 after 20)
Trade Deals: will be worth +40 after 60 turns (was 10 after 20)
Alliance: will be worth +60 after 50 turns (was 40 after 20)
Coalition: worth +40 after 50 turns (was 20 after 20)
Vassal: +0 to start (was 10-60 depending on personality/vassal/master), +30 after 40 turns (was 20 after 20)

Reasons:
War Malus: Removed as it made no sense to lose reputation with someone for being declared war ON
Deals: Diplomacy a long-term game and these changes emphasize that. Trade deals are limited so they've got a diplomatic boost both to encourage researching more of them in the tree and because free trade is a historic sign of friendship.

(cai_personality_diplomatic_event_values_tables)

declaring war: significantly increased base value (-30 to -75), lengthened time to recover from 20/40 (default/resentful) to 30/60
trespassing: lowered time to recover from 20/40 (default/resentful) turns to 10/20
city besieged: recovery time reduced from 20/40 (default/resentful) to 10/20
conquered city: increased diplomatic penalty by 10
starting battle in foreign territory: decreased diplomatic penalty by 5
Marriage: increased effect from 40/60 to 50/75 (default/forgiving) and falloff time from 20/40 to 50 turns.
Non-aggression: lowered initial attitude boost from 20-25 to 5
military access: lowered initial attitude boost from 45-60 to 15
trade deals: Lowered initilal attitude boost from 15 to 5
coalition: Lowered intial boost from 40+ to 25
alliance: Lowered intial boost from 75+ to 40
divorce: Increased penalty to -75/-100 (default/forgiving) for 50 turns from -30/-45 from 20/40 turns. Needed stiff penalty to offset ditching a marriage since it was boosted.

Reasons:
Warmongering is bad. Intended so that it is much worse to declare war and take territories than it is to take them in defense.
Tresspassing lasted too long (5 years...what?) for such a minor offense.
City besieged - somewhat offsetting the war declaration, intended so that winning a defensive war isn't as harmful diplomatically
Marriage - Game of Thrones time! Marriage should be a bigger deal.
Deals: These gains should be bigger the longer they're around, not the shorter


(cai_value_sets_per_strategic_stance_tables)
Increased coercion difficulty as it was too frequently possible to coerce vassalize non-cunning leaders with equal strength (+15 to all values to reject coercions)


(cai_value_sets_per_value_type_tables)
Lowered main threat calculations for creating coalition non-late game to -1 (mainly token value so you know they view as main threat)
Paranoid rulers major threats coalition calculations reduced from -50 to -30
Honorable, trusting, deceitful gain +2 to +5 for creating coalitions
Increased unreasonable offer threshold by -10 for vassalation (meaning you'll require 10 more negative factor points before "unreasonable offer" penalty applies) -> possible to vassalize weak targets you're friendly with

Reasons:
Coalitions: Makes no sense not to want powerful allies...unless you're paranoid. Even if viewed as an enemy - keep them closer than your friends, etc.
Unreasonable Offer: Deals that should have been plausible were impossible. That's not entirely changed, but it is better now. Taking this another step (to -15 or -20) drops the unreasonable offer penalty from too many weak neutral targets so this where it stands.

(cai_value_sets_per_strategic_context_tables)
Increase speculative_strength_mods from 0.1 to 0.2

Vassals who sometimes really should declare independence don't. Should increase vassal independence actions, especially when supported by large power. This needs long-term testing to fine-tune. Am also considering removing diplomatic factors as a consideration for when to declare independence (since vassals of same master often end up buddy buddy it lessens chance greatly) - but not best change IMO.

(cai_variables_tables)
Changed AI to in general be more aggressive but more specifically against nearby rulers.
Views attacking as easier, defending as harder.
Major factions strength consideration raised.

At first glance changing AI behavior may seem out of scope, but these factor in threat calculation which affect how the AI acts diplomatically. AI should now choose better targets.

(campaign_diplomacy_treaty_component_required_treaties_tables)
Should fix vassal treachery.
