That would be "balance," I'd say.
Don't count on buring rams or siege towers. Counter them at the wall/gate. If you can burn them, great. But don't base your defense on that as even cannon towers are very unpredictable at destroying them (if a lot better!) Unfortunately, we get led to believe out fire arrows will be as effective as the AI's. They are not. I estimate they are 1/2 to 1/3 as effective. I've had three rams in a row go up in smoke in one siege, had to withdraw. Meanwhile I'm lucky to burn one in three when defending.
Get high damage melee units on the walls to counter ladders and towers, and stack spears at the gate or breach on "guard." Plow high damage melee units into the flanks of the assaulting troops at the gate/breach. Save cav for emergencies, or wait until they are storming and send them outside from another gate to charge into the rear of the assault force. Nice routs that way.
A few archers are good. Flaming arrows have nice morale effects and killing off some of the arriving troops is always nice. And they can do wall defense in a pinch against less than high-quality troops. They get big defensive bonuses on the walls against storming troops.
At a minimum you can make the enemy pay 3+ to 1 losses for your garrison. You can hold against 1:3 odds with a decently composed garrison, and higher is possible with experienced troops and good generalship. And luck can make a large difference too. The quality of the walls or castle play a role too. As do the more advanced towers.
