Yeah, Battering rams protected by units? WHAT units? Archers'll work. sorta. Anythign else will die before the ram does, then the vills pop out and kill Vills.
I know when their in the TC their not working, but they only have to be in the TC for 3-4 seconds to kill two knights easily. Not to mention, they won' live in fear forever. If your knights are out of LOS, then hey, its safe, or a few pike/spearmen. Archers are even easier. The problem is: Buildings are TOO strong. A TC is too strong. You can't destroy it, becaus eunless you have REAL anti-building weapons(Rams or Magnoals) the player can build villies and garrison them in the TC, shooting arrows. Villies grow FASt. So you can rapidly spring out 3-4 Villies, which gives like, 2-4 arrows. Which each do what, 5 damage? And thats if you killed villies there before.
My mahjor beef: Its not that TCs fire back, or that they make villies, or anything, its: Their Too hard to kill without DEDICATED forces, and their to powerful to leave behind. You may not be able to take a Castle with 4 knights, but you can leave it behind, it won't respawn villagers that can repair it, gather resources or build another Castle. A TC WILL. So you HAVE to destroy it. and its FAR cheaper to build a TC with enough villagers to fire 10 arrows than it is to make a force capable of taking it down. Not to mention the core of the force is extremly slow. Hell, no mater the attacking force, Villies can pop out, kill the Rams(10 villies take a ram out in 6 hits, 15 villies take it out in 3 whaps) then pop in with wounds(40 HPs and 1 point of armor /w loom, thats quite alotta damage soakin' ability) heal up, slaughter the other attackers, or leave a few in the building and go to work, any atatckers come, pop in, slaughter'em, pop out.
A Castle, I don't MIND being strong. But a TC shouldn't need what accounts to a village sacking force in AoE(10+ archers, 2+ siege engines ). Then theres the fact that a Castle likely IS nearby. Damn.
In 75 pop games, you CANT make an offensive army and expect to win against a village. Its impossible. A Castle can kill anything less than a Ram easily with just its 5 natural arrows, God forbid you put archers in it to boost that.
