Rams

[Jayzabala]

I have a problem. When I play a seige battle, attacking or defendig, when a ram aproaches to the walls, and the towers start to fire (when the city have stone walls, of course), the ram always, always is burned. I've tried with 2 or 3 rams at the same time, but i can´t reach the wall, it's always destroyed.
Is it supposed to be in that way? is there any way to do something?.
It´s quite strange that in every seige I have to climb the walls to open the gates.
I'm playing on Hard/Medium.

Rams against stone walls are a bad idea anyway - you will just get toasted by boiling oil when you go through the gates. Use sapping points if you don't want to fight on the walls.

Yes, I know that. and I try to avoid them.
But the AI can´t reach the wall either, and when they only build rams, or rams and a seige tower, the can´t enter ant stands out of the city for 40 minutes, or have a huge army triyng to enter with only one tower. It´s a quite strange situation.
