Ok,after i spent pretty much sometimes in this game,i'm kinda of curious about the battle mechanic. 1:How do you take cities effectively?i found that in this game,sieging a cities is incredibly difficult,especially in early games against greek hoplites,they even easily fend off my stacks of swordsman. 2:How does defense bonus from cities works?is there anyways i can get rid of it?as i said above,it sacrifice too many of my troops just to destroy one hoplites that stands on city walls.Do they also get the defense bonus if they were they one who jumps out to attack me?let say if i surrounded them and were gathering troops for a single strike hoping to take it down in one turn,but they keep on sending force within the city out to kill my newly gathered unit. 3:How does this defense/attack works?cause things never went the way i expected.and would be very questionable about the battle system after you have your tanks getting trashed by some riflemans,or can't figuard out why does it makes pikeman a better defensive unit while my knights has same 3 def but 4 atk,or how does it makes longbow man the better attacker while knights has the same atk but with better speed(thats one of the reason why i build pure knights in early middle-age for both attacker and defender) 4:Sometimes i notice that even when i'm marching on road i still suffers terrain penalties,is it because i'm marching on the enemy's territory? 5:How does Airplant works?i found they are completely useless due to their limited effects and terrible accuracy.
