how having vassal benefit my nation ? do they brake that alliance when crusade or jihad is called ?
does ballista worth having , i think they are just slow,inacurate and do little damage , in short terrible . what u guys think ?
Having vassals almost break the game. You get most of their surplus finances, which combined with the AI finances scripts mean you'll get loads of money constantly.
Ballistas can have their use, depending on the situation. For instance, they can be very overpowered in siege defense. Have a couple of spearmen tie the enemy down, and then have your ballistas fire into the blob of enemy units. Result is quite a lot of dead enemies per shot.
Point your Ballista with fiery bolts at them and watch them running amok!
If enemy is shooting at your walls put your ballista out and shoot at the catapults/siege equipment.
The only real use i have found for vassals is to secure a border indefinitely. However that faction will normally opt for utter destruction then vassal-ship and by the time they do accept it they are normally down to 1 or 2 settlements.
Ballistas really aren't worth the effort, just to inaccurate. Catapults and the exploding barrel things are the best for anti-units.
both ballista and catapults make a killing when you defend in a siege. place first the ballista and behind it the catapult (both on fire & fire at will) on the townsquare as far from the enemy as possible; then make two hedges with spearman on guard (so they won't get in the shooting path), so that the enemy will engage them rather than your ballista or catapult. Use your general or other cav to engage any units that might get through to your ballista or catapult. If you plan it right, they can both get up to +5 experience from the amount of men they kill, and are devastating to the morale of your oponent.
Science flies you to the moon.
Religion flies you into buildings.
Never tried ballistas, but mangonels are very very very effective, specially against a very large army.
Cassius: "Our men at arms have secured the city. We've received representatives from all the best elements. The senate is with us, the knights are with us."
Brutus:"The pontifs, the urban cohorts, the lictors guild..."
Antony: "Oh, the lictors guild, very good. Only rally the bakers and the flute players and you can put on a festival."
I like Ballistas. I use my catapults to bring down walls and then put my Ballistas in a position where they have a nice shot on units covering up the hole the Catapults made; the result? A lot of dead enemy units, allowing my Infantry to come in and finish the job off.
