The crossbow units avaiable to recruit in Sicily (Gastraphetes: http://www.honga.net/totalwar/rome2/...R_10_Crossbows), as romans even without auxillia barracks, are imo overpowered. By now, they are my favourite ranged weapon units, here's why:
- At the begin of the battle I place them in front of my legions because they seem to be more effective when dont have to shoot over someones head. Because of their armor penetration skill they make serious damage to either elite units or even take out the enemy cavalry.
- When the melee battle begins, I place them behind my infantry line and let them shoot the enemy cavalry (if theres any left) thats trying to flank, with deadly outcome for enemy cavalry.
- After shooting off the enemy cavalry I use them to flank the enemy lines myself and shoot their infantry in the back - deadly outcome for enemy. I dont even flank with my reserve units or my own cavalry because of friendly fire, also the crossbows are more effective.
- Once the enemy army routs I even send my crossbows in melee attack mode to hunt down the enemy. Deadly outcome to the enemy, beacuse the crossbows are fast units.
- I make 200-300 kills per crossbow unit (at normal unit size) per battle.
Possible solutions:
a) Reduce the speed of these units. Crossbow units where always slow. (Is it possible to make ranged weapon units as slow as heavy melee infantry?)
b) Reduce the ammunition, so you have to decide weither you take out the enemy elite units or the cavalry. They seem to have more crossbow ammo than archers have.
c) Make them only aviable after some reforms - dont know if Im correct, but recruiting crossbow units 200 B.C. feels strange for me. I know late roman armies had crossbows, but I think it was only late like 300 A.D.
Feel free to post your opinion and feel free to recruit an complete army of crossbows and play like it's Empire: Total War
