I have not played this game since 2015, now because of the situation around I remembered about it and started playing again. With so much new stuff can you give me a crash course of what I need to focus on to be able to take part in world wars? Currently my base is a mess, it's 97 level Enlightment, Romans. Apperantly my strategy in 2015 was to use Riders only in attack so balista, mortar, gatling gun those I have not unlocked yet... What troop should I upgrade, what researches, in university what to do? I am looking for the most efficient way to become strong in attack.
