AI is still too timid when attacking.
Germany declared war on me in a deity game, he had a good unit composition, artillery, machine guns, knights. All corps. Surrounded my city, good unit movement, shelling my city defences, then in a few turns he sues for peace...
Granted, the turn after he declared I teched civil engineering for 200 defence, then turn after I teched field cannons and upgraded a few crossbow men, but still he could of easily taken that city..
Hopefully there is an easy fix to the code where the AI is an bit more confident on attack. unit comp, movement etc. seems good
