So far all I’ve seen is that instead of damaging the spearwall became something like a stopping zone. Placing spearwalls on the sides of the wall formation makes the enemies go in middle or start going the long way around. When placed in terrain chokepoints the enemies still do try to approach it. It became more of a tactical choise now than a widespread use. It did not change anything for me, was already using only 2 spearman placed on tactical approach points. But it might have change up a lot for people who were using it’s damage advantage heavily.
