I tried to use the pikemen for the first time, and assumed that the spear wal was, just like the phalanx, an impenetrable block of spears, but I noticed that it didn't do much to stop enemy charges and if you take them off defensive stance, they don't even stay in a spearwall formation. Am I doing something wrong? The spearwall in defensive stance does nothing besides looking impressive, they don't hold formation, and stop enemies with their spears like phalanxes would do in RTW, as soon as a heavy cavalry unit charges them the formation is disrupted and they lose their effectiveness. I should add that I used them as a gate defenders in a siege defence against mongolian invaders, seeing how the general has a tendency to charge in first, I figured 3 of these pike units at the gate would finnish him and anything that came after him off without problems, but they, as mentioned earlier, turned out useless
