The AI seems to be making questionable choices. They will double or triple core world in a super small area. Makes them not able to produce ships quick enough and makes their cores weak.
More problematic is there desire to strike at my undefended areas. Which while they are undefended the AI can’t get to them with my flanking screens in place it keeps throwing single ships at me and while I got them hilariously and hopeless outgunned I’m barely even taking damage but if the AI put fleets together to fight my fleets I might lose a few ships but they are just gifting me experience and having near zero impact.
