For point 3, i meant those archers in the towers, they helped me sometimes in sieges for getting rid of units on the wall, so i wanted to know how to control them. In one custom battle, i was as the Julii, defending against Carthage. Their siege towers wiped out my archers on the wall before breaching the wall itself. So i thought i could try that too.
For point 5, i can keep them loyal enough, the problem is no matter how much i focus on economy, i cant get a good income. I even built temples for happiness so that i could increase tax, but it didnt work.
But thanks a lot for the help for the other ponits!!!
