Many people have found issue with Total War: Rome II, mainly with how the AI fails to pose much of a challenge. Almost all Total War games have a bumpy start however, and The Creative Assembly always does their best to fix their games as quickly as possible.
The released fourth patch for Rome II aims at improved the way AI behaves in the game, both in battle and outside. The highlights include how AI builds armies, how it researches upgrades, and improves general difficulty. Diplomacy is minorly touched upon and the full patch notes can be found at the Total War wiki.
