So I frecuently find that AI factions wasting their potential research in the diplomacy field to improve diplomacy with factions they have a negative bias about, factions that are very far away or factions they are trying to conquer anyway later.
It seems a little tweaking would help the AI to become more competitive and field better ships.
AI should spent less research potential on factions with:
A: Negative predisposition
B: Far away
C: Conquer targets
This first screen is from Dhayut later mid game and second is Teekan. Dhayut have brutal research but Teekan way less than player and their ships are really lackluster still invested a ton of potential research into diplomacy.
