Cannons, ah the smell of gunpowder the sounds of the blasts the chaos the screams the agony!!! Oh yeah.
Well when I think of cannons I think of the siege units in AOK somewhat like Heavy Scorpions are the nasty anti-infantry siege there will be a anti-infantry cannon or light cannon.
Siege Onager well you will probably have a bigger more inacurate cannon but with better attack that can kill even cavalry (if they can hit it), and also because of its size it does fairly well vs buildings and other siege, medium cannon tipe.
And the last one, the pice of resistace, the trebs. They were the most powerfull unit in the game in point of attack, inacurate vs units but in large numbers 30 or more (yeah I saw those much trebs and more) they can be deadly, but they do great vs buildings.
Now that is how I imagine the big anti-buildings cannon, huge inacurate vs units but awsome vs buildings a heavy cannon.
I think I will love cannons cause I am a michi player with a great love of siege .
I can imagine it now, a huge battle, infantry, cavalry cannons you name it, the enemy has 2 times my force in army but not many cannons. I am stuck in my town the enemy is bombing the hell out of me, now when he thinks he has got me he moves in with his infantry not observing my own cannons. Sudenly all my cannons go of infantry units are getting killed 10-15 at a time. The enemy sends his cavalry to get me now, but the my medium cannons open fire and with the aid of the light cannons cause an incredible barage of fire that just overwhelms the cavalry anihilating them.Now that would be an awsome battle
