Towers

Whats better for nof camp ?

ballista or mangonel ? With Ballista you can shoot as well in any of enemy catapult which enemy make in random places (put every ballista as group #.. and shoot with them in personal enemy catapult). Mangonel perfect use when enemy have too much siege weapons, also troops in attack.

Is it good idea to make crossbowmen ? Towers are good but in 160x160 maps only. - by MW

Whats best place to make tower, near wall or near eco ? Best place to make tower in castle near economy because you have place make walls before tower, also you can repair tower and you can put archers/ crossbowmen on tower(if want). Also you can make catapults before tower. And you will have same game situation like attacker.

P.S.: Trebuchets in big walls also better make in castle near economy against attack massive catapults+monks, because monks can't stay in same pixels where stay catapults after 2 seconds.
